Question

for closed system difference between the heat added to the system and work done by the gas is​

Answer 1

For a closed system, the difference between the heat added to the system and the work done by the system is equal to the change in enthalpy,entropy,temperature, internal energy

Answer 2

Hey buddy,

● Answer -
For closed system, difference between the heat added to the system and work done by the gas is​ equal to 'change in internal energy'.
Q - W = ∆U

● 1st law of thermodynamics -
The First Law of Thermodynamics states that energy can be converted from one form to another with the interaction of heat, work and internal energy, but it cannot be created nor destroyed, under any circumstances.

In simple words, change in internal energy is equal to heat added to the system minus work done by system.
∆U = Q - W
