A closed system participates in the following process: `A to B to C`. In the step `AtoB`, heat absorbed by the system =q cal and in the step `B to C`, heat released by the system=q cal. Therefore, in this process the sum of the heat absorbed and heat released by the system is zero. is this an adiabatic process? Given reason.

Explanation

In an adiabatic process, the system does not exchange heat with its surroundings at any step in the sprocess. In the given process, the system absorbs heat in one step and releases heat in other step. So, this process cannot be regarded as an adiabatic process.
