A quartz tube contains one mom of gAs at 20 deg c. The gas is heated at constant volume to 300 deg c. How much thermal energy is transferred to the gas? If the same amount were heated at constant pressure, how muh energy would be required?
I know how to solve this for constant volume using E= 3/2 nRT to get 3490.2 j but I don't know what difference constant pressure makes?
