Question

. A gas cylinder contains 30 liters of diatomic nitrogen gas at 273 K and a pressure of 140 atm. If the temperature is increased to 300 K, how much will the internal energy of the gas increase?

Answer 1

If the temperature is increased to 300 K, the gas molecules will have an increase in kinetic energy. This will increase the internal energy of the gas as kinetic energy is one type of internal energy. However, the pressure will also increase as the gas molecules hit the walls of the cylinder with more force. This increase in pressure will decrease the internal energy of the gas as it takes more energy to compress the gas molecules.
