Which thermodynamic process takes place at a constant temperature so that the internal energy of a system remains unchanged? A.
the isovolumetric process
B.
the isobaric process
C.
the adiabatic process
D.
the isothermal process

D

Explanation:

Isothermal process is one that occurs on constant temperature example the vaporisation of water on boiling in an enclosed space .

At this time the temperature of the system remains constant .
