Question

Δ U is equal to

  • Isochoric work

  • Isobaric work

  • Adiabatic work

  • Isothermal work

Answer

C.

Adiabatic work

From 1st law thermodynamics:
ΔU = q + w
For adiabatic process :
q = 0
∴ ΔU = w
∴ Work involves in the adiabatic process is at the expense of a change in internal energy of the system.
