Question 18: Thermodynamics & KTG

Question

Assertion : Molar heat capacity cannot be defined for isothermal process.
Reason : In isothermal process $$p$$-$$V$$ versus $$T$$ graph is a dot.

Accepted Answer

$$C=\frac{Q}{m \Delta T}$$
In isothermal process $$\Delta T=0$$. Therefore, $$C$$ is not defined further in isothermal process $$p V$$ and $$T$$ both are constants.

Answer

Both assertion and reason are true and reason is the correct explanation of assertion

Answer

Both assertion and reason are true but reason is not the correct explanation of assertion

Answer

Assertion is true but reason is false

Answer

Both assertion and reason are false.
