An ideal monatomic gas originally at a pressure of 3x10⁵ Pascals and 75 moles and volume 1.2 m³ & T_i is expanded isothermally to a volume of 3.5 m³ at which point it has pressure P₁. It then experiences an isovolumic process to a lower pressure P₂, T₂. Finally, it is compressed adiabatically back to its original state and returns to its original pressure, temperature, and volume.

Find:

T_i , P₁ , P₂ , T₂

ΔE_{1 of gas}, ΔE_{2 of gas} , ΔE_{3 of
gas} , ΔE_{Total of gas}

W₁_{by gas}, W_{2 by gas}, W_{3 by
gas}, W_{Total by gas}

Q_{1 into gas}, Q_{2 into gas}, Q_{3 into
gas}, Q_{Total into gas}

_{Answers should be:}

Ti = 577.62 Kelvin, P1 = 102,857.14 Pascals, P2 = 50,206.54 Pascals, 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, Q3 into gas = 0 Joules, QTot into gas = 108.95 kJoules
