Question

An ideal gas undergoes an isothermal expansion. Let Q, W, and ?U be the heat absorbed by the gas, work done by the gas, and the change in internal energy of the gas during the process, respectively. Which one of the following is true? Q<0, W<0, ?U=0 Q>0, W>0, ?U=0 Q=0, W>0, ?U>0 Q=0, W>0, ?U<0 Q>0, W>0, ?U>0
