A Carnot cycle is conducted using an ideal diatomic gas. Initially, the gas is at temperature 25C., pressure of 100KPa and volume of 0.01m3. The system is then compressed isothermally to a volume 0.002m3. From that point, the gas undergoes an adiabatic compression ( with gamma= 1.4), until the volume further reduces to 0.001m3. After that, the system goes an isothermal expansion process to a point where the pressure of the system is 263.8KPa. Then the system continues the cycle...
A system consists of 2.320 g of carbon monoxide gas initially at temperature 400.0 K and pressure 0.6250 bar. Assume the heat capacity of carbon monoxide is constant at the value found for 298.15 K in the data tables of the Appendix (see also Figure 2.8). The system undergoes the following cyclic process: Step a) Reversible isothermal expansion to double the initial volume. Step b) Constant volume extraction of heat from the system (to a temperature and pressure consistent with...

4. The pressure-volume diagram below shows a special reversible cycle called the Carnot cycle A mole of an ideal gas starts off in state 1 in contact with a large thermal reservoir at temperature Th. The gas then undergoes an isothermal expansion from Vi to V2. Upon reaching state 2, the gas container is removed from contact with the thermal reservoir and covered with thermal insulation. Next the gas is allowed to expand adiabatically from V2to Vs. Because the expansion...
Problem 2: In a given lab session a group of students performed a sequence of thermodynamic processes to a given gas. Before performing the process the studenta recorded the initial pressure of the gas as being 101.5 kPa and its temperature equal to 2000 The sequence can be described as firstly isochoric heating in which the gas temperature is increased by 25% of its initial temperature, followed by an isothermal compression in which the volume of the gas is reduced...
