The First Law of Thermodynamics is a restatement of which fundamental conservation law?

During an adiabatic process, there is no exchange of heat between the system and surroundings. Therefore, which of the following is correct?

The efficiency ($\eta$) of a Carnot engine working between source temperature $T_1$ and sink temperature $T_2$ (in Kelvin) is given by:

For an adiabatic process of an ideal gas, the equation of state relating pressure $P$ and volume $V$ is:

How is the coefficient of performance ($\beta$) of a refrigerator related to the efficiency ($\eta$) of a Carnot heat engine operating between the same temperature limits?

Which of the following processes is strictly irreversible?

The slope of an adiabatic $P$-$V$ curve at a given point is how many times the slope of an isothermal $P$-$V$ curve at the same point?

A system absorbs $500\text{ J}$ of heat and performs $200\text{ J}$ of work. What is the change in internal energy of the system?

Is it possible to construct a heat engine that converts $100%$ of absorbed heat into mechanical work? Which law prohibits this?
