Consider a container with a frictionless piston that contains a given amount of an ideal gas. If the external pressure is kept constant, the piston will move up or down in response to a change in the internal pressure. The piston will move up if Pint > Pext and vice versa. The piston will stop moving when Pint = Pext (the system is equilibrated). The container has 1.2 mol of an ideal gas initially at 22 °C and the system is in equilibrium with an external pressure of 1.2 bar. The gas is slowly heated to a final temperature of 342 °C. During this process, the piston is allowed to move if necessary to keep the system at equilibrium (that is, the internal pressure is allowed to match the external pressure at all times). The molar heat capacity at constant volume Cum of this ideal gas is 2.5 R. Part A - Calculate the initial volume of the gas. Express your answer in m³ with 3 significant figures. Part B - Calculate the final volume of the gas. Express your answer in m³ with 3 significant figures. Part C Calculate w, the work involved in the process. Part D- Calculate q, the amount of heat exchanged in the process. Consider a container with a frictionless piston that contains a given amount of an ideal gas.
