A) isometric process.
B) isobaric expansion.
C) adiabatic expansion.
D) isothermal expansion.

Answer 1

During an adiabatic expansion process, the work done by the gas is zero.

Step-by-step explanation:

The work done by the gas is zero during an adiabatic expansion.

In an adiabatic process, the system is insulated from its environment, so no heat is allowed to enter or leave the system. When a gas expands adiabatically, it does work against the outside world, but since there is no heat transfer, the net change in the internal energy of the gas is zero. As a result, the work done by the gas is zero. The work done by the gas is zero during an isometric process. In such a process, the volume of the gas does not change. No work is done because work in thermodynamic processes is generally given by the product of pressure and the change in volume (W = p∆V), and since the change in volume (∆V) is zero in an isometric process, the work (W) is also zero.
