The gas is in the standard temperature and pressure condition i.e. at S.T.P Hence V1 = 22.4 dm3 and V2 have to be calculated. As given expansion is isothermal and…
One mole of an ideal gas is heated at constant pressure from 0oC to 200oC. (a) Calculate work done. (b) If the gas were expanded isothermally & reversibly at 0°C…
We know that for an ideal gas, work done w is given as: Wideal = -nRT ln (V2/ V1) And for a a van der Waals Gas, work done is…
The cutting of trees in the hilly areas has lead to decrease in the absorption of water. The increase in soil erosions and the aggregation of water during rainy seasons…
These are also known as the marine resources. The oceans cover around 70 percent of the earth surface. The oceans are still unexplored and they have large resources. The land…
They occupy nearly 20 percent of the earth surface. It covers around 13000 million hectares of the area. The houses, roads and factories occupy nearly one third of the land.…
The formation of soil occurs by the process of weathering and soil development. The weathering is further divided into the physical and chemical types. It is basically a destructive process…
There are many factors which play a role in the conversation of soil. In order to conserve the soil the top most layers must be preserved. It is the ideal…
These are the natural resources which cannot be renewed. They are present in the organisms as an organic and inorganic molecule and ions. The calcium, phosphorous, sodium, chlorine and sulphur…
