One mole of an ideal monatomic gas, Cᵥ = (3/2)R, is taken through the cycle represented by states 1 to 4 as shown in Figure 6. At state 1, P₁ = 1.01 x 10⁵ Pa, V₁ = 0.0225 m³ and T₁ = 273 K. At state 3, T₃ = 1092 K.

One mole of an ideal monatomic gas, Cᵥ = (3/2)R, is taken through the cycle represented by states 1 to 4 as shown in Figure 6. Assume that at state 1, P₁ = 1.01 x 10⁵ Pa, V₁ = 0.0225 m³ and T₁ = 273 K and at state 3, T₃ = 1092 K. Calculate
