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...

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?

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.

Consider a closed system consisting of one mole of a monoatomic ideal gas X initially at 10.0 atm, a temperature of 487.5 K, and a volume of 4.00 L (state A). From state A, the system may expand isothermally and reversibly to state B, where the pressure is 2.50 atm. The system may also expand adiabatically and reversibly to state B, where the pressure is 2.50 atm. The system may also expand adiabatically and reversibly (through an intermediate state D)...

A sample of 1.00 mol of N2 gas is expanded adiabatically from a volume of 10.00 dm3 and a temperature of 400 K to a volume of 20.00 - 3 -dm3. Assume that nitrogen is ideal, with Cv,m = 5R/2. (i) Find the final temperature if the expansion is carried out reversibly. (ii) Calculate the final temperature if the expansion is carried out with a constant external pressure of 1.00 atm. (iii) Find the final temperature if the gas expands...

A 2.00 mol sample of an ideal gas with a molar specific heat of CV = 5 2 R always starts at pressure 1.50 ✕ 105 Pa and temperature 250 K. For each of the following processes, determine the final pressure (Pf, in kPa), the final volume (Vf, in L), the final temperature (Tf, in K), the change in internal energy of the gas (ΔEint, in J), the energy added to the gas by heat (Q, in J), and the...

a monoatomic ideal gas originally occupies a volume of 3.0 L and then expands to a new volume of 3.0 L and then expands to a new volume of 24.0 L if the final pressure of the gas is 1 atm and the change in entropy of the gas during expansion is zero, what must have been the inital pressure of the gas (Hint: it may help to determine the ratio of final to inital temperature Tf/Ti) Please any help...

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...
