(select all that apply)    Temperature may change.    Pressure may change    Volume may change    Mass may change    Internal energy may change    Potential energy may change    No system property may change

What is the first law of thermodynamics?

Define first law of thermodynamics and explain it ?

Apply the second law of thermodynamics to cycles and cyclic devices.

Give the description of the following basic concepts of thermodynamics: System, closed systems, open systems, isolated systems, intrinsic and heat energy of a working fluid,

A working substance enters a thermodynamic steady flow system with the following conditions:P1 = 20 Psia; v1 = 11.7 ft3, u1=101.6 Btu/lb, V1=150 ft/sec. The working substance leaves the system with the following conditions: p2=25 psia, v2 = 10.3 ft3/lb u=149.0 Btu/lb and V2 = 500 ft/sec. Changes through the system are negligible and 10 Btu/lb transferred head is added to the fluid as it passes through the system. Determine the work done on or by the fluid in Btu/lb.

The following processes occurs in a reversible thermodynamic cycle:   1-2: Reversible polytropic compression at pressure 0.6 bar at volume 0.07 m3 to a pressure 10.2 bar and specific volume 0.4 m3/kg. The index of compression may be taken as n. 2-3: Reversibly expansion with expansion index of 2 to pressure 3 bar. 3-1: Reversible cooling at constant volume to the initial state.      Calculate the value of n in the process to 3 decimal places.

The following processes occurs in a reversible thermodynamic cycle:   1-2: Reversible polytropic compression at pressure 0.7 bar at volume 0.07 m3 to a pressure 11 bar and specific volume 0.6 m3/kg. The index of compression may be taken as n. 2-3: Reversibly expansion with expansion index of 2 to pressure 2.5 bar. 3-1: Reversible cooling at constant volume to the initial state.  Calculate the work for the expansion in the process to 2 decimal places.  Not in kilo or mega of unit.
