A gas is compressed adiabatically. Which statement is NOT true?

Question

G1 Physics · Accepted Answer

For an adiabatic process, Q = 0 During compression, work is done on the gas. Using ΔU = Q + W(on), we get ΔU = W(on) > 0 So internal energy increases and temperature rises. Therefore the statement 'there is no change in internal energy' is false. Hence option A follows.
