Question

prove that internal energy is property of system​

Answer 1

Answer:

We can also say that energy will always be conserved. Heat and work, these are two different forms of energy. If heat energy is provided to the system by the surrounding then system may provide the work energy to the surrounding and similarly if work is being done upon the system then system may deliver the energy in terms of heat to the surrounding.

Hence, this is the basic concept of first law of thermodynamics. Now we will see here the detailed explanation behind the statement that energy as property of the system and as point function too. After that, in our next post, we will see first law of thermodynamics for an open system or control volume.

Let us assume that we have one system which is undergoing a change of state from initial state 1 to another state 2 via following the path A as shown in following figure. System is returning to initial state i.e. state 1 from state 2 via following the path

Answer 2

Answer:

If heat energy is provided to the system by the surrounding then system may provide the work energy to the surrounding and similarly if work is being done upon the system then system may deliver the energy in terms of heat to the surrounding. Hence, this is the basic concept of first law of thermodynamics.
