An ideal gas with Cp = 20 J/mol K is compressed from P₁ = 1 bar, T₁= 273 K, and V₁ = 10 m³ to a final pressure P₂ = 20 bar and V ₂¹ = 2 m³ using the following mechanically reversible processes: Isothermal compression followed by heating at constant volume. Calculate Q, W, AU and the additional properties required in the table below for each of this process. The following sketch (NOT to scale) illustrates the two steps for this process. T(K) = T (°C) + 273.15 R= 8.3145 J/K mol R= 8.3145x105 m³ bar/K. mol PV=nRT 1 bar=1KN/m²=100 KJ/m³ 1 Joule = 1 N.m P₂ p* P₁ 2 (*,2) Isochoric V₂ (1, *) Isothermal 1 V₁ Write your final answers in the following table T₂ T₁ E3 (*,2) Isochoric (1, *) Isothermal V₂ 1 V₁
