First law state that neither energy generate nor destroyed but can change its forms.

Thermodynamics first low state that Energy can be neither created nor destroyed, if can only changes forms any process in an isolated system, the total energy remains the same.

What?
Probably you are talking of thermodynamics in another universe.
So how can you explain the increase of temperature in a system composed by a certain mass of substance when heat is supplied.
The total energy of the substance remains constant?

These questions have not been written out properly. I was so confused that I got the answer wrong. This answer is only true for an isolated system like the universe.

The first law of thermodynamics states that total energy of universe remain constant. If we take any particular system than there may be change in total energy of system in case of irreversible process.

According to first law energy can neither be created nor be destroyed it can be change from one form to another form.

First law is state that the law of conservation of energy. Energy can neither be created nor be destroyed but only converted one for to another form.

The energy of the universe is constant not the system if not be specified that the system is what?

Answer is true because such as law not write in any books. We are depends on book. But it may be possible books is wrong?
