A system absorbs 600J of heat and work equivalent to 300J on its surroundings. The change in internal energy is:

Calculate the internal energy change for each of the following processes: (i) A system absorbs 428 J of heat and does work equivalent to 286 J on its surroundings. (ii)62 J of work is done on the system and 128 J of heat is transferred to the surroundings.

Heat and work are ''definite quantities''. Heat and work are not properties of a system. Their values depend on the path of the process and vary accordingly.

Statement-1: Work and Heat are two equivalent form of energy. Statement-2: Work is transfer of mechanical energy irrespective of temperature-differene whereas heat is transfer of thermal energy because of temperature difference only.
