Choose the correct options for the following statements :

On compressing a gas suddenly, its temperature 

When we switch on the fan in a closed room, the temperature of the air molecules :

A polyatomic gas $$\left ( \gamma =\dfrac{4}{3} \right )$$ is compressed to $$\dfrac{1}{8}$$ of its volume adiabatically. If its initial pressure is P, the new pressure will be

A quantity of heat ‘Q’ is supplied to a mono-atomic ideal gas which expands at constant pressure. The fraction of heat that goes into work done by the gas is:

A given mass of a gas is compressed isothermally until its presssure is doubled. It is then allowed to expand adiabatically until its original volume is restored and its pressure is then found to be 0.75 of its initial pressure. The ratio of the specific heats of the gas is approximately :

The pressure and density of a given mass of a diatomic gas ($$\gamma = \dfrac{7}{5}$$) change adiabatically from (P, d) to (P$$'$$, d$$'$$). If $$\dfrac{d'}{d}= 32$$,  then $$\dfrac{P'}{P}$$ is 
($$\gamma =$$ ratio of specific heats)

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

A monatomic ideal gas initially at $$17^{o}C$$ is suddenly compressed to $$\dfrac{1}{8}$$ of its original volume. The temperature after compression is

The tyre of a motor car contains air at 15 degree Celsius, if the temperature increases to 35 degree celsius, the approximate percentage increase in pressure is (ignore to expansion of tyre):
