The pressure of a gas is increased four times and its absolute temperature two times. The ratio of its final volume to its initial volume is

A gas at 627$$^{0}$$ C is cooled so that its pressure becomes $$\dfrac{1}{3}$$ of its initial value at constant volume. Its final temperature is 

At 27$$^{0}$$ C certain gas occupied a volume of 4 litres. If the volume of this is to be increased to 12 litres at the same pressure, the gas is to be heated to a temperature

A P-V diagram is obtained by changing the temperature of the gas as shown. During this process the gas is :

For an isochoric process the temperature at which the pressure of a gas will be double that of its pressure at 270$$^{0}$$ C is

A car tyre has air at 1.5 atm at 300 K.If P increases to 1.75 atm with volume same, the temperature will be ____

The volume of a gas is 5 litres at N.T.P. what will be its volume at 273$$^{0}$$ C and at a pressure of four atmospheres 

A gas at 27$$^{0}$$C and pressure of 30atm is allowed to expand to atmospheric pressure and volume 15 times larger. The final temperature of gas is

At 20$$^{o}C$$ temperature and 1atmosphere pressure if a gas has a volume of 293 ml .Its volume at NTP is

A sample of an ideal gas occupies a volume V at pressure P and absolute temperature T. The mass of each molecule is m. The equation for density is
