2 a) An ideal gas with a Cv of 1.5R independent of temperature is initially contained in a volume of 0.05 L at a pressure of 10 atm and an initial temperature of 1200°C. The volume is then increased to 0.50 L. What will be the final pressure and temperature of the gas if the total amount of gas is unchanged, and the gas undergoes reversible adiabatic expansion? How much work will be produced? Calculate the change in entropy of...

A monatomic ideal gas is initially at volume, pressure, temperature (Vi, Pi, Ti). Consider two different paths for expansion. Path 1: The gas expands quasistatically and isothermally to (Va, Pz. T2) Path 2: First the gas expands quasistatically and adiabatically (V2, P.,T-),where you will calculate P T. Then the gas is heated quasistically at constant volume to (Va. P2 T1). a. Sketch both paths on a P-V diagram. b. Calculate the entropy change of the system along all three segments...

A flexible balloon contains 0.350 mol of an unknown polyatomic gas. Initially the balloon containing the gas has a volume of 6900 cm3 and a temperature of 30.0 ∘C. The gas first expands isobarically until the volume doubles. Then it expands adiabatically until the temperature returns to its initial value. Assume that the gas may be treated as an ideal gas with Cp=33.26J/mol⋅K and γ=4/3. What is the total heat Q supplied to the gas in the process? What is...

There are n moles of an ideal gas at initial volume Vi and initial temperature Ti. The gas undergoes an external heating in which an amount of energy Q enters the gas in the form of heat. The gas expands isobarically to a new volume ½ If Q=2x10), n=13.8mols, T1-201.8K, И = 1.4m3, and ½= 1.9m3, what work done by the gas during this expansion? Answer in Joules. Answer:

4. [After Reif Problem 5.1] When an ideal gas undergoes an adiabatic (thermally insu- lated) quasi-static expansion, its pressure and volume are related by p = constant. where γ = cp/cv is the ratio of heat capacities. If the gas expands from an initial volume Vi at temperature T to a final volume V2, calculate the final temperature T2 in terms of γ, Vi, Ti, and ½.
