Volume of the gas at the end of the second step (adiabatic expansion) will be nearly

How does the temperature of the gas change?

For an adiabatic compression the quantity $$PV$$

An ideal gas of adiabatic exponent $$\gamma$$ is expanded so that the amount of heat transferred to the gas is equal to the decrease of its internal energy. Then the equation of the process in terms of the variables $$T$$ and $$V$$ is

In an adiabatic change, the pressure $$P$$ and temperature $$T$$ of a diatomic gas are realtion $$P\, \propto\, T^{\alpha}$$ where $$\alpha$$ equals

A mass of gas is first expanded isothermally and then compressed adiabatically to its original volume. What further simplest operation must be performed on the gas to restore it to its original state ?

The given figure shows the variation of force applied by ideal gas on a piston which undergoes a process during which piston position changes from $$0.1$$ to $$0.4 m$$. If the internal energy of the system at the end of the process is $$2.5 J$$ higher, then the heat absorbed during the process is

A cycle pump becomes hot near the nozzle after a few quick strokes even if they are smooth because

A gas obeys the relation $$\displaystyle V\propto \dfrac { 1 }{ { T }^{ 2 } } $$. The $$\dfrac{ C_p }{C_v}$$ value for the gas is

The amount of energy required to change the temperature of $$1\ kg$$ of a substance by $$1^\circ C$$  is called _________.
