A fixed mass system completes a heating process at constant

A fixed mass system completes a heating process at constant volume with no work. Since energy is conserved (E2 - E1 = 1Q2 - 1W2) the system energy at the final state must be -- A less than the initial value B equal to the initial value C greater than the initial value D any value is possible

Solution

Ans : C

For the closed system, the conservation of energy principle or the first law of thermodynamics is expressed as

E_in - E_out = deltaE _system

According to classical thermodynamics, we consider the energy added to be net heat transfer to the closed system and the energy leaving the closed system to be net work done by the closed system .

Q_net - W _net = delta E

Normally the stored energy, or total energy, of a system is expressed as the sum of three separate energies. The total energy of the system, Esystem, is given as

E = internal energy + Kinetic energy + Potential energy

E = U + KE + PE
