Q1. A gas with molar mass 46 kg/kmolK and mass 0.056 kg ·is cooled at constant volume of 0.0046 m³ from 281 K to 1/2 its original pressure. It is then isentriopically compressed according to PV^γ = C to ½ of its original volume

(a) Sketch PV and Ts diagrams.

(b) 1Calc·ulate the specific gas constant.

(c) Find the heat transfer during the initial process.

(d) Calculate EACH of the following:

(i) the final temperature.

(ii) the isentropic work done.

Note: R_u = 8.,314 kJ/kmol K and C_V = 451 J/kgK
