	A balloon contains $500\,{{m}^{3}}$ of helium at 27°C and 1 atmosphere pressure. The volume of the helium at – 3°C temperature and 0.5 atmosphere pressure will be
	A vessel contains 1 mole of ${{O}_{2}}$ gas (molar mass 32) at a temperature $T$. The pressure of the gas is $P$. An identical vessel containing one mole of $He$ gas (molar mass 4) at temperature $2T$ has a pressure of
	1 mole of gas occupies a volume of 100 ml at 50 mm pressure. What is the volume occupied by two moles of gas at 100 mm pressure and at same temperature
	For ideal gas, which statement is not true
	A given mass of a gas is allowed to expand freely until its volume becomes double. If ${{C}_{b}}$ and ${{C}_{a}}$ are the velocities of sound in this gas before and after expansion respectively, then ${{C}_{a}}$ is equal to
	Kinetic theory of gases was put forward by
	One litre of Helium gas at a pressure 76 cm of Hg and temperature $27^o C$ is heated till its pressure and volume are doubled. The final temperature attained by the gas
	A flask is filled with 13 gm of an ideal gas at $27^o C$ and its temperature is raised to $52^o C$. The mass of the gas that has to be released to maintain the temperature of the gas in the flask at $52^o C$ and the pressure remaining the same is
	The molecular weight of a gas is 44. The volume occupied by 2.2 g of this gas at and 2 atm. pressure will be
