A monatomic ideal gas has pressure p1 and temperature T1. It is contained in a cylinder of volume V1 with a movable piston, so that it can do work on the outside world. Consider the following three-step transformation of the gas:The gas is heated at constant volume until the pressure reaches Ap1 (where A>1).The gas is then expanded at constant temperature until the pressure returns to p1.The gas is then cooled at constant pressure until the volume has returned to V1.It may be helpful to sketch this process on the pVplane. How much heat Q1 is added to the gas during step 1 of the process?Express the heat added in terms of p1, V1, and A. How much work W2 is done by the gas during step 2?Express the work done in terms of p1, V1, and A. How much work W3 is done by the gas during step 3?If you've drawn a graph of the process, you won't need to calculate an integral to answer this question. Express the work done in terms of p1, V1, and A.

Air is held within a frictionless piston-cylinder container, which is oriented vertically. the mass of the piston is 0.45 kg and the cross-sectional area is 0.0030 m2. initially (state 1) the pressure of the gas is sufficient to support the weight of the piston as well as the force exerted by the atmospheric pressure ( 101.32 kpa). the volume occupied by the air within the cylinder in state 1 is 1.00 liter. one end of a spring (with spring constant k = 1000 n/m) is attached to the top of the piston, while the other end of the spring is attached to a stage that can move vertically. initially the spring is undeflected and therefore exerts no force. then the stage is then moved quasistatically downward a distance of 10.0 cm, at which point the system reaches state 2. the piston-cylinder is not insulated; rather it remains in diathermal contact with the surroundings, which are at a constant temperature of 300 k. what is the change of pressure within the container?

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)
