Three moles of nitrogen at 30°C are contained in a container of a certain volume. If we ignore the heat capacity of this container, how much heat should we apply to the system to raise the temperature of nitrogen to 250°C? If the mass of the container is 100 kg and the heat capacity is 0.5 kJ/(kg°C), what is the required heat? At this time, nitrogen is Cv=20.8 and Cp=29.1 J/(mol°C).
