What will be the effect on the density of $0.09 \ mol$ of a gas at $300 \ K$ if its pressure is increased?

Which of the following equations does $NOT$ represent Charles's law for a given mass of gas at constant pressure?

The compressibility factor of an ideal gas is

If a sample of neon gas at $75^{\circ}C$ is cooled such that its volume decreases by $15\%$,to what temperature (in $^{\circ}C$) should it be heated so that its pressure becomes double?

Equal amounts of gases are kept in two separate containers. If the densities of the two gases are in $1:2$ ratio and their temperatures are in $2:1$ ratio, calculate the ratio of their respective pressures.

At what pressure will a quantity of gas occupy a volume of $60 \, mL$,if it occupies a volume of $100 \, mL$ at a pressure of $720 \, mm$ (assuming temperature is constant)?
