Question 11: Thermodynamics & KTG

Question

Assertion In isothermal process, whole of
the heat energy supplied to the body is
converted into internal energy.
Reason According to the first law of
thermodynamics,
$$\Delta Q=\Delta U+\Delta W$$

Accepted Answer

As there is no change in internal energy of
the system during as isothermal change. Hence,
the energy taken by the gas is utilised by doing
work against external pressure.
Hence, whole heat energy gapping to the body at
isothermal process converted into work done.
Hence, Assertion is wrong.
