SSC JE Mechanical Engineering 2017 Set 2 Solved Paper

The enthalpy of a system is equal to the system's internal energy plus the product of its pressure and volume.
Th enthalpy of a thermodynamic system is defined as H = U + pV,
where,
H is the enthalpy of the system,
U is internal energy of the system,
p is the pressure of the system,
V is the volume of the system.
