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...
A 0.450-mol sample of an ideal diatomic gas at 372 kPa and 312 K expands quasi-statically until the pressure decreases to 147 kPa. Find the final temperature and volume of the gas, the work done by the gas, and the heat absorbed by the gas if the expansion is the following. (a) Isothermal final temperature _______ volume of the gas _______ work done by the gas _______ heat absorbed _______ (b) adiabatic final temperature _______ volume of the gas _______ work done by the gas _______ heat absorbed _______
Consider an ideal gas that initially has a pressure of 1909kPa and a volume of 11.0L. The gas in compressed at constant pressure to a volume of 7.00L. Heat is then added at constant volume until the pressure reaches 3 ⇥ 103kPa. Draw the process on a P-V diagram and calculate: the work done; the change in internal energy; the heat flow (into/out of the gas)
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. The gas consequently expands slowly from an initial volume of 10 m3 to 15 m3. (a) Draw a P-V diagram for this process. (b) Is this thermodynamic process an isothermal expansion, an isobaric expansion or an adiabatic expansion? (c) Calculate the work done by the gas. (d) Calculate...
