The volume of a certain amount of gas changes isothermally from `V_(1) "to" V_(2)` . What will be the work done?

(i) 1 mol of an ideal gas expands isothermally and reversible from (P_(1)V_(1)T) to (P_(2)V_(2)T) . Write down the equation showinig the amount of heat absorbed by the given ideal gas. (ii) In an isothermal expansion of an ideal gas, the pressure of the gas decreases from P_(1) to P_(2) . write down the equation of work done by the gas in this process. (iii) The temperature of 1 mol of an ideal gas is increased from T_(1) and T_(2) . write down the equations for the changes in enthalpy and internal energy.

The temperature of a fixed mass of an ideal gas is changed from T_(1)K to T_(2)K(T_(2) > T_(1)) . Calculate the work done if the change is brought about at (i) constant pressure (ii) constant volume. Hence find from the first law of thermodynamics, in which case heat absorbed will be greater.
