Question

In an isothermal change of an ideal gas, Δ U=0. The change in heat energy Δ Q is equal to (A) 0.5 W (B) W (C) 1.5 W (D) 2 W

Tardigrade Admin · Accepted Answer

According first law of thermodynamics, Δ Q=Δ U+Δ W ⇒ Δ Q=0+W=W

Q. In an isothermal change of an ideal gas, $Δ U = 0$ . The change in heat energy $Δ Q$ is equal to
