A monatomic ideal gas undergoes isothermal expansion from 0.08 m3 to 0.22 m3 at a constant temperature (initial pressure is 310 kPa). What are its (a) internal energy change (ΔEΔE), (b) net heat transfer (Q), and (c) net work done (W)? Use negative quantity for heat transfer out of the system or work done on the system.
2. Isochoric/Adiabatic/Isobaric Cycle (10 pts) A heat engine using a monatomic gas follows the cycle shown in the PV diagram to the right. Between stages 1 and 2 the gas is at a constant volume, and between 2 and 3 no heat is transferred in or out, between 3 and 1 the pressure is held constant (a) For each stage of this process, calculate in Joules the heat, Q, transferred to the gas, and the work, W, done by the...
An ideal monatomic gas is contained in a cylinder with a movable piston so that the gas can do work on the outside world, and heat can be added or removed as necessary. The figure shows various paths that the gas might take in expanding from an initial state whose pressure, volume, and temperature are , , and respectively. The gas expands to a state with final volume . For some answers it will be convenient to generalize your results...
A gass undergoes adiabatic expansion to a pressure of 760 Pa and a volume of 7.5 m3 . The gas then undergoes isothermal compression to a volume of 4m3 . The gas then undergoes an isochoric process and returns to 1800 Pa of pressure. (Find Q,W, delta U for this isochoric process.) a) Find Q b) Find W c) Find delta U
7.5) A 1.15 -mol quantity of monatomic ideal gas undergoes the following cyclic process. The gas starts at point a at STP. It expands isothermally to point b, where the volume is 2.2 times its original volume. Next, heat is removed while keeping the volume constant and reducing the pressure. Finally, the gas undergoes adiabatic compression, returning to point a. a. Calculate the pressures at b and c. (answers in Pa) **Find the volumes at a and b first. **Use...
A polytropic process for an ideal gas in one in which pressure and volume are related by = const., where n is a constant. It is a generalization of the special processes considered earlier. Thus n = 0 defines an isobaric process, n = cp/cv an adiabatic process, n = 1 an isothermal process, and n = 8 an isochoric process. Suppose 1 kg of dry air at 280 K and 100 kPa undergoes a polytropic expansion in which the...
400 moles of an ideal monatomic gas are kept in a cylinder fitted with a light frictionless piston. The gas is maintained at the atmospheric pressure. Heat is added to the gas.
