if possible please answer all questions

A cylinder that contains 0.062 kg of carbon dioxide (with molar mass 44 kg/kmol), occupying a volume of 0.027 m3 at 1.1 bar is compressed reversibly until the pressure is 6.6 bar. If the molar (universal) gas constant as 8.3145 kJ/kmol K, calculate the the work done on the C02 (in J) when the process is isothermal.

Identify the working substance, specify the kind of system and sketch the system boundary. Please answer it in 1hr.

This is a Thermodynamics question. Please explain nicely. Considering variable specific heats, find the entropy change of a piston cylinder assembly containing airas an ideal gas and going through the following process:   V1=1m3T1=27 C V2=1.7m3T2= 327 C

3. Air is contained within a piston-cylinder assembly The cross sectional area of the piston is 0.01 m². Initially the piston is at 1 bar and 25°C, 10 cm above the base of the cylinder. In this state, the spring exerts no force on the piston. The system is then reversibly heated to 100°C. As the spring is compressed, it exerts a force on the piston according to: F=-kx where k= 50,000 N/m and x is the displacement length from its uncompressed position. Determine the work done. a. -166 J b. -216 J c. 166 J d. 216 J

There are 2.27 kg/min of steam undergoing an isothermal process from 3 Bar, 316o C to 7 Bar. Determine (a) ΔS, ΔU and Δ (b) Determine Q and W for a nonflow process, and (c) for steady flow process with ΔK = 0. Use and draw T-s diagram.

Refrigerant 134a at p1 = 30 lbş/in?, T1 = 40°F enters a compressor operating at steady state with a mass flow rate of 250 lb/h and exits as saturated vapor at p2 = 160 lbę/in?. Heat transfer occurs from the compressor to its surroundings, which are at To = 40°F. Changes in kinetic and potential energy can be ignored. The power input to the compressor is 2.5 hp. Determine the heat transfer rate for the compressor, in Btu/hr, and the entropy production rate for the compressor, in Btu/hr-°R.

Refrigerant 134a at p1 = 30 lbe/in?, T1 = 40°F enters a compressor operating at steady state with a mass flow rate of 400 Ib/h and exits as saturated vapor at p2 = 160 Ib/in?. Heat transfer occurs from the compressor to its surroundings, which are at To = 40°F. Changes in kinetic and potential energy can be ignored. The power input to the compressor is 4 hp.
