An ideal gas at pressure $ P $ is adiabatically compressed so that its density becomes $ n $ times the initial value. The final pressure of the gas will be $ \left(\gamma = \frac{C_{P}}{C_{V}}\right) $

A quantity of a substance in a closed system is made to undergo a reversible process from an initial volume of $ 3 \,m^3 $ and initial pressure $ 10^5\, N/m^2 $ to a final volume of $ 5\, m^3 $ . If the pressure is proportional to the square of the volume (i.e. $ p = AV^2 $ ), the work done by the substance will be

In a container, $200 \,g$ of aluminum (specific heat $900\, J / kg K$ ) at $100^{\circ} C$ is mixed with $50\, g$ of water at $20^{\circ} C$, with the mixture thermally isolated. Find the entropy change of the aluminumwater system.

Starting with the same initial conditions, an ideal gas expands from volume $ {{V}_{1}} $ to $ {{V}_{2}} $ in three different ways. The work done by the gas is $ {{W}_{1}} $ if the process purely isothermal, $ {{W}_{2}} $ if purely isobaric and $ {{W}_{3}} $ if purely adiabatic. Then

1 mole of an ideal gas expands isothermally so that its pressure falls $ 1.0 \times {{10}^{5}} $ Pa to $ 0.5\times {{10}^{5}} $ Pa. The change in entropy of the gas is equal to

A thermodynamic state of a given sample of an ideal gas is completely described, if its
