An engine using 1 mol of an ideal gas initially at 22.3 L and 454 K performs a cycle consisting of four steps: 1) an isothermal expansion at 454 K from 22.3 L to 40 L ; 2) cooling at constant volume to 270 K ; 3) an isothermal compression to its original volume of 22.3 L; and 4) heating at constant volume to its original temperature of 454 K . Find its efficiency. Assume that the heat capacity is...

An ideal gas is allowed to expand isothermally until it reaches its final volume. It is then heated at constant volume until it reaches its final pressure. The initial state of the gas is P1 = 2.93 atm, V1 = 1.00 L, and Eint 1 = 414 J, and its final state has volume V2 = 2.93 L and Eint 2 = 951 J. 1) Calculate the work done by the gas. Be careful with signs: if the work you...

Professor Modyn owns another piston-cylinder device, which initially (State 1) contains 0.236 m3 of saturated water vapor at 400.0 kPa. Heat is now slowly transferred to the steam until the volume doubles. Consider the expansion a two step process. First, constant volume heating occurs until the pressure reaches 500.0 kPa (State 2). Finally, a constant pressure expansion occurs resulting in the doubling of the initial volume (State 3) Note: The IUPAC sign convention for work is used. Work into the...
