In a process ` A to B to C to D`, the heat absorbed by the system in the steps `A to B and B to C` are `q_(1) and q_(2)`, respetively, and the heat released by the system in the stp `C to D` is `q_(3)`. If `q_(1)+q_(2)+q_(3)=0`, then will the process be adiabatic?

Explanation

In adiabatic process, heat is not exchanged between a system and its surroundings at any stage of the process. In the given process, heat is being exchanged between the system and the surroundings. Thus, the process is not adiabatic though the sum of the amounts of heat absorbed and released in zero for the process.
