One mole of an ideal gas expands at a constant temperature of \(300\;K\) from an initial volume of 10 litre a to a final volume of 20 litres. The workdone in expanding the gas is
371583
Heat is added to an ideal gas and the gas expands. In such a process the temperature
1 Must always increase
2 Will remain the same if the work done equals the heat added
3 Must always decrease
4 Will remain the same if change in internal energy equals the heat added

For an isothermal process, I. Pressure of a given mass of a gas varies inversely as its volume. II. During expansion of gas, work is done by the gas on environment. III. During compression heat is released Choose the correct statement
1 Only II
2 Both I and II
3 Both II and III
4 I, II and III
Explanation:
For an isothermal process, temperature is fixed, so \(p V=\text { constant } \Rightarrow P \propto \dfrac{1}{V}\) In an isothermal expansion, gas absorbs heat and does work on the environment. In an isothermal compression, work is done on the gas by the environment and heat is released. So, option (4) is correct.
