Question

Which thermodynamic process takes place when work is done on or by the system but no energy is transferred to or from the system as heat?

Answer 1

Step-by-step explanation:

Adiabatic process is the process which occurs without the exchange of heat and mass between system and surrounding. There is exchange of energy only as a work in adiabatic process.

Application of adiabatic Process

• From first law of thermodynamics

`Q=\Delta U+W`

For adiabatic Process
`Q=0`

`W=-\Delta U`

so work done is change in internal energy of the system
