Acylinder with a movable piston contains 20.5 moles of a monatomic ideal gas at a pressure of 2.86 × 105 pa. the gas is initially at a temperature of 300 k. an electric heater adds 58600 j of energy into the gas while the piston moves in such a way that the pressure remains constant. it may you to recall that cp = 20.79 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. what is the temperature of the gas after the energy is added?
