Physics

An ideal monatomic gas originally at a pressure of3x105 Pascals and 75 moles and volume 1.2 m3& Ti is expanded isothermally to a volume of 3.5m3 at which point it has pressure P1. It thenexperiences an isovolumic process to a lower pressureP2, T2. Finally, it is compressedadiabatically back to its original state and returns to itsoriginal pressure, temperature, and volume.

Find:

Ti , P1 , P2 ,T2

ΔE1 of gas, ΔE2 of gas , ΔE3 ofgas , ΔETotal of gas

W1by gas, W2 by gas, W3 bygas, WTotal by gas

Q1 into gas, Q2 into gas, Q3 intogas, QTotal into gas

Answers should be:

Ti = 577.62 Kelvin, P1 = 102,857.14 Pascals, P2 = 50,206.54Pascals, T2 = 281.95 Kelvin

ΔE1 of gas = 0 Joules, ΔE2 of gas = -276.41 kJoules, ΔE3 of gas= 276.41 kJoules, ΔETot of gas = 0 Joules

W1 by gas = 385.36 kJoules, W2 by gas = 0 Joules, W3 by gas =-276.41 kJoules, WTot by gas = 108.95 kJoules

Q1 into gas = 385.36 kJoules, Q2 into gas = -276.41 kJoules, Q3into gas = 0 Joules, QTot into gas = 108.95 kJoules
