What is the change in internal energy of the system

Reference no: EM13557071

A closed system undergoes a constant pressure process from state 1 to state 2. The volume of the system is doubled from 1 m^3 to 2 m^3 while 200 kJ of heat is added to the system. If no work is done except for the boundary displacement work and the pressure remains constant at 101.3 kPa (1 atm) throughout the process,

(a) what is the change in internal energy of the system? Assume the displacement work in a (fully resisted) constant pressure process is given by (*sub 12 means from stage 1 to 2) Wsub12=p(Vsub2-Vsub1).

(b) develop an algebraic expression for the heat added in terms of properties of the system assuming a quasi-equilibrium constant pressure process.
