x.Hmle="text-align: left; margin-bottom: 1.8em; margin-left: 0.9em; "> 1)Q Joules of heat are added to n moles of an ideal gas at either a constant pressure or a constant volume. For which case will the change in the internal energy of the gas be greater? 1) Change in internal energy is greater at constant volume. 2) Change in internal energy is the same for constant p process and constant V processes. 3) Change in internal energy is greater at constant pressure. 1)Q Joules of heat are added to n moles of an ideal gas at either a constant pressure or a constant volume. For which case will the change in the internal energy of the gas be greater? 1)Q Joules of heat are added to n moles of an ideal gas at either a constant pressure or a constant volume. For which case will the change in the internal energy of the gas be greater? Change in internal energy is greater at constant volume. Change in internal energy is the same for constant p process and constant V processes. Change in internal energy is greater at constant pressure. 1) Change in internal energy is greater at constant volume. 2) Change in internal energy is the same for constant p process and constant V processes. 3) Change in internal energy is greater at constant pressure.Explanation / Answer
The change in internal energy is greater at consatntvolume when we given heat energy at constant volume then workdone is zero ,so the total amount is useful to increaseinternal energy. Where as at consatnt pressure the given heatenergy is useful to both internal energy and workdone. The ideal heat engine has an efficiency of one.Related Questions
