Assertion :For an isothermal process in an ideal gas, the heat obsorbed by the gas is entirely used in the work done by the gas Reason: During a process taking place in a system, if the temperature remains constant then the process is isothermal.

Solution
The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Since in an isothermal process the temperature remains constant, there is no change in internal energy of the system.Thus whole of heat absorbed is used entirely in the work done by the gas.The definition of the isothermal process is also true. But the definition has got nothing to do with conversion of thermal energy entirely into work done.
