NEET Physics Question - Thermal Physics

Assertion (A): In adiabatic process, work done on the system is equal to negative of change in internal energy.

Reason (R): In adiabatic process change of heat zero.

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

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

In an adiabatic process, the system is perfectly insulated so that no heat exchange occurs \( $Q = 0$ ). According to the First Law of Thermodynamics \( $\Delta U = Q - W_{by}$ ), this means any change in internal energy is due entirely to work: \( $\Delta U = -W_{by}$
