About First Law of Thermodynamics
The first law relates heat supplied, work done and the change in internal energy through energy conservation. Problems use sign conventions and apply the law to isothermal, adiabatic, isobaric and isochoric processes. Internal energy is a state function, while heat and work depend on the path followed.

In which process, the change in internal energy of the system is zero?
Heat neither enters nor leave a system then its temperature:
A monoatomic gas (γ=5/3) is suddenly compressed to 1/8 of its original volume adiabatically, then the pressure of the gas will change to:
The first law of thermodynamics may be expressed as shown: ∆U=Q+W Where ∆U is the change of internal energy, Q is the heating of the system, W is the work done on the system. A fixed mass of ideal gas at high pressure is contained in a balloon. The balloon suddenly bursts, causing the gas to expand and cool. In this situation, which row describes the values of ∆U, Q and W?
A gas undergoes the cycle of pressure and volume changes W --> X --> Y --> Z --> W shown in the diagram. What is the net work done by the gas? What is the net work done by the gas? What is the net work done by the gas? What is the net work done by the gas?
Heat added at constant volume of a gas is used to:
