A heat engine using a monatomic gas follows the cycle shown in the pV diagram. P11 The gas starts out at point 1 with a volume of V1 = 318 cm", a pressure of p1 = 147 kPa, and a temperature of 317 K. The gas is held at a constant volume while it is heated until its temperature reaches 455 K (point 2). The gas is then allowed to expand adiabatically until its pressure is again 147 kPa (point...

A cylinder of monatomic ideal gas is sealed in a cylinder by a piston. Initially, the gas occupies a volume of 2.50 L and the pressure is initially 125 kPa. The cylinder is placed in an oven that maintains the temperature at a constant value. 80.0 J of work is then done on the piston, compressing the gas (in other words, the gas does -80 J of work). The work is done very slowly so that the gas maintains a...
