An ideal gas undergoes isothermal compression from an initial volume of 5.28 m3 to a final volume of 2.89 m3. There is 6.41 mol of the gas, and its temperature is 11.4°C. (a) How much work is done by the gas? (b) How much energy is transferred as heat between the gas and its environment?
Two mole of ideal gas, is compressed adiabatically in a piston/cylinder device from 2 bar and 25oC to 7 bar. The process is irreversible and requires 25% more work than a reversible, adiabatic compression from the same initial state to the same final pressure. What is the entropy change of the gas? Assume Cv=(5/2)R in this calculation.
Problem 8: Consider the reversible Carnot's cycle of an ideal monatomic gas in the cold cylinder of 290 K corresponding to the isothermal compression step. Then the volume of the gas is further compressed by a factor of 7.5 in the adiabatic compression step. a) Find the temperature at the final step of the adiabatic compression. b) What is Thot for the isothermal expansion step? c) What is the maximum thermodynamic efficiency for this engine? d) How much would the...
Please give detailed explanation for final part. Thanks. Reversible adiabatic expansion of ideal gas (This question involves working through the final section of lecture 3) Explain why the first Law for an reversible adiabatic process gives AU = -PdV, and why this equation doesn't hold for the Joule expansion. Assuming that for an ideal gas U = CVT, prove that the First Law leads to the statement that PVY is constant in a reversible adiabatic process. A container of Helium...
In both cases below, one mole of an ideal gas is expanded from an initial volume V to a final volume 2 V. In both cases, the gas is identical and the initial pressure is 2P. The expansion is adiabatic in A and isothermal in B. Will the final temperature of the gas be (i) greater in Case A, (ii) greater in Case B, or (iii) the same in both cases? Explain your reasoning

2. One mole of an ideal gas, CP - (7/2)R and CV - (5/2)R, is compressed adiabatically in a piston/cylinder device from 2 bar and 25°C to 7 bar. The process is irreversible and requires 35% more work than a reversible, adiabatic compression from the same initial state to the same final pressure. What is the entropy change of the gas?
(a) An ideal gas initially at pressure po undergoes a free expansion until its volume is 5.30 times its initial volume. What then is the ratio of its pressure to po? (b) The gas is next slowly and adiabatically compressed back to its original volume. The pressure after compression is (5.30)1/3po. Is the gas monatomic, diatomic, or polyatomic? (c) What is the ratio of the average kinetic energy per molecule in this final state to that in the initial state?...
