Consider an ideal gas in a 4.46 x 10–3 m3 closed container initially at a temperature of 284 K and a pressure of 1.27 x 105 Pa. How many moles of gas are present? If the ideal gas is reduced to 1.02 x 105 Pa of pressure isochorically (i.e. at constant volume), what is its new temperature? If the ideal gas is then expanded isobarically (i.e. at constant pressure) by raising its temperature back to 284 K, what is its new volume? Draw these two processes on the pV diagram below labeling the pressures and volumes accurately.
