A tank with a constant volume of 5.89 m3 contains 15 moles of a monatomic ideal gas. The gas is initially at a temperature of 300 K. An electric heater is used to transfer 56500 J of energy into the gas. It may help you to recall that CVCV = 12.47 J/K/mole for a monatomic ideal gas, and that the number of gas molecules is equal to Avagadros number (6.022 × 1023) times the number of moles of the gas.

1)What is the temperature of the gas after the energy is added?

2)What is the change in pressure of the gas?Pa

3)How much work was done by the gas during this process?
