A fluid system undergoes a non-flow frictionless process following the pressure-volume relation as p = 10 / V + 3 where p is in bar and V is in m3. During the process the volume changes from 0.3 m3 to 0.1 m3 and the system rejects 90 kJ of heat. Determine :(i) Change in internal energy ;(ii) Change in enthalpy

Basic Thermodynamic Processes

The word 'thermodynamics' can be divided into two words, 'thermo' and 'dynamics'. The word thermo deals with the heat and thermal phenomenon, whereas dynamics deals with forces or external agent that drives the heat flow or aids in the motion of heat.
