Between andalmost half a million indentured labourers arrived from India at Aapravasi Ghat to work in the sugar plantations of Mauritius, or to be transferred to Reunion Island, Australia, southern and eastern Africa or the Caribbean.Pressure Temperature and Volume Gas Law Relationship
The buildings of Aapravasi Ghat are among the earliest explicit manifestations of what was to become a global economic system and one of the greatest migrations in history. Le Morne Cultural Landscape Le Morne Cultural Landscape, a rugged mountain that juts into the Indian Ocean in the southwest of Mauritius was used as a shelter by runaway slaves, maroons, through the 18th and early years of the 19th centuries.
Island of Mozambique The fortified city of Mozambique is located on this island, a former Portuguese trading-post on the route to India. Its remarkable architectural unity is due to the consistent use, since the 16th century, of the same building techniques, building materials stone or macuti and decorative principles. Most of these well-preserved engravings represent rhinoceros.
The site also includes six painteelephant, ostrich and giraffe, as well as drawings of human and animal footprintsd rock shelters with motifs of human figures in red ochre.

The objects excavated from two sections, date from the Late Stone Age. The site forms a coherent, extensive and high-quality record of ritual practices relating to hunter-gatherer communities in this part of southern Africa over at least 2, years, and eloquently illustrates the links between the ritual and economic practices of hunter-gatherers.
Covering an area of over three million hectares and a buffer zone ofhectares, the site is composed of two dune systems, an ancient semi-consolidated one overlain by a younger active one.
The desert dunes are formed by the transportation of materials thousands of kilometres from the hinterland, that are carried by river, ocean current and wind. It features gravel plains, coastal flats, rocky hills, inselbergs within the sand sea, a coastal lagoon and ephemeral rivers, resulting in a landscape of exceptional beauty.
The reserves boast an outstanding variety of landscapes, plant species and wild animals. It includes the largest and most important continuum of terrestrial, semi-aquatic and aquatic ecosystems in the West African savannah belt. The property is a refuge for wildlife species that have disappeared elsewhere in West Africa or are highly threatened.
It is home to the largest population of elephants in West Africa and most of the large mammals typical of the region, such as the African Manatee, cheetah, lion and leopard. It also harbours the only viable population of lions in the region.
The historic centre of the city, an important crossroads of the caravan trade, is divided into 11 quarters with irregular shapes.
The site is marked by ancestral cultural, commercial and handicraft traditions still practiced today and presents exceptional and sophisticated examples of earthen architecture.
Sukur Cultural Landscape The Sukur Cultural Landscape, with the Palace of the Hidi Chief on a hill dominating the villages below, the terraced fields and their sacred symbols, and the extensive remains of a former flourishing iron industry, is a remarkably intact physical expression of a society and its spiritual and material culture.
Osun-Osogbo Sacred Grove The dense forest of the Osun Sacred Grove, on the outskirts of the city of Osogbo, is one of the last remnants of primary high forest in southern Nigeria. Regarded as the abode of the goddess of fertility Osun, one of the pantheon of Yoruba gods, the landscape of the grove and its meandering river is dotted with sanctuaries and shrines, sculptures and art works in honour of Osun and other deities.
The sacred grove, which is now seen as a symbol of identity for all Yoruba people, is probably the last in Yoruba culture.
It testifies to the once widespread practice of establishing sacred groves outside all settlements. From the 15th to the 19th century, it was the largest slave-trading centre on the African coast. Ruled in succession by the Portuguese, Dutch, English and French, its architecture is characterized by the contrast between the grim slave-quarters and the elegant houses of the slave traders. Today it continues to serve as a reminder of human exploitation and as a sanctuary for reconciliation.
Niokolo-Koba National Park Located in a well-watered area along the banks of the Gambia river, the gallery forests and savannahs of Niokolo-Koba National Park have a very rich fauna, among them Derby elands largest of the antelopeschimpanzees, lions, leopards and a large population of elephants, as well as many birds, reptiles and amphibians.
Djoudj National Bird Sanctuary Situated in the Senegal River delta, the Djoudj Sanctuary is a wetland of 16, ha, comprising a large lake surrounded by streams, ponds and backwaters. It forms a living but fragile sanctuary for some 1. Island of Saint-Louis Founded as a French colonial settlement in the 17th century, Saint-Louis was urbanised in the midth century.

It was the capital of Senegal from to and played an important cultural and economic role in the whole of West Africa. The location of the town on an island at the mouth of the Senegal River, its regular town plan, the system of quays, and the characteristic colonial architecture give Saint-Louis its distinctive appearance and identity.
Saloum Delta Fishing and shellfish gathering have sustained human life in the 5, km2 property, which is formed by the arms of three rivers. The site comprises brackish channels encompassing over islands and islets, mangrove forest, an Atlantic marine environment, and dry forest. The site is marked by shellfish mounds, some of them several hundreds metres long, produced by its human inhabitants over the ages.
Burial sites on 28 of the mounds take the form of tumuli where remarkable artefacts have been found. They are important for our understanding of cultures from the various periods of the delta's occupation and testify to the history of human settlement along the coast of West Africa.

Bassari, Fula and Bedik Cultural Landscapes The site, located in south-east Senegal, includes three geographical areas: The Bassari, Fula and Bedik peoples settled from the 11th to the 19th centuries and developed specific cultures and habitats symbiotic with their surrounding natural environment.
The Bassari landscape is marked by terraces and rice paddies, interspersed with villages, hamlets and archaeological sites. The Bedik villages are formed by dense groups of huts with steep thatched roofs. The site is a well-preserved multicultural landscape housing original and still vibrant local cultures.
Aldabra Atoll The atoll is comprised of four large coral islands which enclose a shallow lagoon; the group of islands is itself surrounded by a coral reef. Due to difficulties of access and the atoll's isolation, Aldabra has been protected from human influence and thus retains somegiant tortoises, the world's largest population of this reptile. The famous coco de mer, from a palm-tree once believed to grow in the depths of the sea, is the largest seed in the plant kingdom.
Fossil Hominid Sites of South Africa The Taung Skull Fossil Site, part of the extension to the site inscribed inis the place where in the celebrated Taung Skull — a specimen of the species Australopithecus africanus — was found. Makapan Valley, also in the site, features in its many archaeological caves traces of human occupation and evolution dating back some 3.
Plug in the values: The Temperature-Volume Law This law states that the volume of a given amount of gas held at constant pressure is directly proportional to the Kelvin temperature. V Same as before, a constant can be put in: Also same as before, initial and final volumes and temperatures under constant pressure can be calculated.
The Pressure Temperature Law This law states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. P Same as before, a constant can be put in: The Volume Amount Law Amedeo Avogadro Gives the relationship between volume and amount when pressure and temperature are held constant.
Remember amount is measured in moles. Also, since volume is one of the variables, that means the container holding the gas is flexible in some way and can expand or contract. If the amount of gas in a container is increased, the volume increases. If the amount of gas in a container is decreased, the volume decreases.
V As before, a constant can be put in: The Combined Gas Law Now we can combine everything we have into one proportion: This process is repeated until either there is no more room in the open arm or the volume of the gas is too small to be measured accurately. This relationship between the two quantities is described as follows: Dividing both sides of Equation 6. The numerical value of the constant depends on the amount of gas used in the experiment and on the temperature at which the experiments are carried out.
Boyle's law - Wikipedia
At constant temperature, the volume of a fixed amount of a gas is inversely proportional to its pressure. Boyle used non-SI units to measure the volume in. Hg rather than mmHg. Because PV is a constant, decreasing the pressure by a factor of two results in a twofold increase in volume and vice versa. The Relationship between Temperature and Volume: Charles's Law Hot air rises, which is why hot-air balloons ascend through the atmosphere and why warm air collects near the ceiling and cooler air collects at ground level.
Because of this behavior, heating registers are placed on or near the floor, and vents for air-conditioning are placed on or near the ceiling. The fundamental reason for this behavior is that gases expand when they are heated. Because the same amount of substance now occupies a greater volume, hot air is less dense than cold air.
The substance with the lower density—in this case hot air—rises through the substance with the higher density, the cooler air.
