For nitrogen gas the values of cv and cp at 25°c are 20.8 j k−1 mol−1 and 29.1 j k−1 mol−1, respectively. when a sample of nitrogen is heated at constant pressure, what fraction of the energy is used to increase the internal energy of the gas? how is the remainder of the energy used? the remainder of the energy is used to the volume of the gas against the constant pressure. how much energy is required to raise the temperature of 138.2 g n2 from 25.0°c to 86.0°c in a vessel having a constant volume? kj
