Question

Assertion : The specific heat of a gas in an adiabatic process is zero and in an isothermal process is infinite.

Reason : Specific heat of gas is directly proportional to change of heat in system and inversely proportional to change in temperature.

(a) Both A and R are true and R is the correct explanation of A

(b) Both A and R are true but R is not correct explanation of A

(c) A is true but R is false

(d) A and R are false

Answer 1

Correct option (a) Both A and R are true and R is the correct explanation of A

Explanation :

In adiabatic process, no heat transfer takes place between gas and surrounding

From definition of specific heat,

Again, for isothermal process
