Question

ΔU is equal to ____________ work.

Options

• isochoric

• isobaric

• adiabatic

• isothermal

Answer 1

ΔU is equal to adiabatic work.

Explanation:

In an adiabatic process, no heat is allowed to enter or leave the system. Hence, Q = 0.

According to the first law of thermodynamics,

ΔU = Q + W

∴ ΔU = W
