Question

In an adiabatic process internal energy of gas _______

Answer 1

Adiabatic process:-

1. It is a thermodynamic process, in which there is no transfer of heat and matter between the outside surroundings and the thermodynamic system.
2. In this process, there is less work done and no heat flow.
3. So, temperature decreases, and there would be a decrease in the internal energy ( $∆\mathrm{U}$ ).

Therefore, In an adiabatic process internal energy of gas decreases.
