Figure below shows pressure (P) versus volume(V) graphs for a certain mass of a gas at two constant temperatures $$T_1$$ and $$T_2$$. Which of the inferences given below is correct?

An ideal gas at $${27}^{o}C$$ is compared adiabatically to $$\dfrac{8}{27}$$ its original volume [$$T{V}^{\gamma-1}=$$constant] and $$\gamma=\dfrac{5}{3}$$, then the rise in temperature will be:

Which of the following parameters does not characterise the thermodynamic state of matter?

A gas expands adiabatically at constant pressure, such that its temperature $$T \propto \frac{1}{\sqrt{V}}$$. The value of $$C_p / C_V$$ of the gas is:

The pressure $$p$$, volume $$V$$ and temperature $$T$$ for a certain gas are related by $$p=\dfrac{AT-BT^2}{V}$$, where $$A$$ and $$B$$ are constants. the work done by the gas when the temperature changes from $$T_1$$ to $$T_2$$ while the pressure remains constant, is given by:

A thermodynamic system is taken from an original state to an intermediate state by the linear process shown in the figure. Its volume is then reduced to the original value from $$E$$ to $$F$$ by an isobaric process. Calculate the total work done by the gas from $$D$$ to $$E$$ to $$F$$. 

In an adiabatic change, the pressure and temperature of a monoatomic gas are related as $$P\propto {T}^{C}$$, where $$C$$ equals

In an adiabatic change, the pressure and temperature of a monoatomic gas are related with relation as $$P\propto {T}^{C}$$, where $$C$$ is equal to :

An ideal gas is compressed isothermally until its pressure is doubled and then allowed to expand adiabatically to regain its original volume ($$\gamma=1.4$$ and $${2}^{-1.4}=0.38)$$. The ratio of the final to initial pressure is
