consider the following two statements.
(A) If heat is added to a system, its temperature must increase.
(b) if positive work is done by a system in a thermodynamic process, its volume must increase.

Consider the following statements and choose the correct answer. a) if heat is added to a system, its temperature must always increase. b) if positive work is done by a system in thermodynamics process, its volume must increase.

If positive work is done on a system, its energy

"When heat is added to a system, the internal energy of the system must increase". Justify this statement.

Heat is supplied to a system, but its internal energy does not increase Obtain an expression for the work done in the above process.

If DeltaU and Delta W represent the increase in internal energy and work done by the system resectively in a thermodynamical process, which of the following is true?

If DeltaU and Delta W represent the increase in internal energy and work done by the system respectively in a thermodynamical process, which of the following is true?

If DeltaU and Delta W represent the increase in internal energy and work done by the system resectively in a thermodynamical process, which of the following is true?
