Property of system which depend only on the state of the system and not on the path.Example: Pressure, volume, temperature, internal energy, enthalpy, entropy etc.
1 Q at constant pressure menas sum of change in internal energy and work done....
2. q at constant volume means change in internal energy
3. W at adiabatic condition means, zero heat energy, i.e. change in internal energy
4. W at isothermal means, zero internal energy, i.e equals to heat given,although works depends on initial and final parameters.
