An ideal gas at STP is contained in a thermally insulated chamber A, connected by a valve to an identical evacuated chamber B. Upon opening the valve, the gas expands into chamber B. Which thermodynamic variable remains constant during this process?

An ideal gas is heated at constant pressure and absorbs amount of heat $Q$. If the adiabatic exponent is${\rm{\gamma }}$, then the fraction of heat absorbed in raising the internal energy and performing the work, in

A gas undergoes a thermodynamic process where its volume remains constant. Which of the following statements is TRUE about this process?

Two containers A and B of equal volume are connected by a valve. Container A holds an ideal gas at standard temperature and pressure (STP), while container B is completely evacuated. The entire system is thermally insulated. If the valve is opened suddenly, what type of thermodynamic process occurs?

Ten moles of an ideal gas at constant temperature 600 K is compressed from 100 L to 10 L. The work done in the process is

A gas expands under constant pressure P from volume ${V_1}$ to ${V_2}$. The work done by the gas is

The specific heat of a gas

A monoatomic ideal gas at 300 K is compressed isothermally to half its initial volume. The same gas, starting at the same initial conditions, is compressed adiabatically to half its initial volume. What is the final temperature of the gas in the adiabatic process?

2 g of water condenses when passed through 40 g of water initially at ${25^{\rm{o}}}{\rm{C}}$. The condensation of steam raises the temperature of water to ${54.3^{\rm{o}}}{\rm{C}}$. What is the latent heat of steam?

A gas undergoes a process where no heat enters or leaves the system. What type of process is this?

The change in the entropy of a 1 mole of an ideal gas which went through an isothermal process from an initial state $({p_1},{V_1},T)$ to the final state $\left( {{p_2},{V_2},T} \right)$ is equal to
