Which of the following process possess a change in internal energy of the system?
Open in App
Solution
The correct option is C Adiabatic
In
thermodynamics, the internal energy of a system is the energy contained
within the system, excluding the kinetic energy of motion of the system
as a whole and the potential energy of the system as a whole due to
external force fields. It keeps account of the gains and losses of
energy of the system that are due to changes in its internal state.
In case of isothermal, free expansion and cyclic process there
is no change in the internal energy of the system as system's
temperature remains constant in these processes. As internal energy is a
function of temperature, there is no change in the internal energy of
the system.
Here in Adiabatic process there is a change in the internal energy of the system.
