A certain mass of gas occupies a volume of 300 cc at 27\,^\circ C and 620 mm pressure. The volume of this gas at47\,^\circ C and 640 mm pressure will be

A gas occupies a volume of 2 liters at a pressure of 1 atm. According to Boyle’s Law, what will be the approximate volume of the gas at a pressure of 0.5 atm, assuming the temperature remains constant?

The density of a gas $A$ is twice that of a gas $B$ at the same temperature. The molecular weight of gas $B$ is thrice that of $A$. The ratio of the pressures acting on $A$ and $B$ will be

Gay-Lussac’s law of combining volume is applicable for those gases which on mixing:

Equal volumes of two gases, A and B, at the same temperature and pressure effuse through a pinhole. Gas A effuses twice as fast as gas B. What is the ratio of the molar masses of B to A?

To what temperature must a neon gas sample be heated to double its pressure, if the initial volume of gas at75\,^\circ C is decreased by 15.0%?

Solid ${\rm{C}}{{\rm{H}}_4}$ is:

Air at sea level is dense, this is a practical implementation of

At constant volume, the pressure of a gas is directly proportional to its:
