The Gas Laws

In a closed flask of 5 litres, 1.0 g of  ${\mathrm{H}}_2$ is heated from 300 K to 600 K. Which statement is not correct?

A bubble of air is underwater at temperature  ${15}^{o}C$ and the pressure 1.5 bar. If the bubble rises to the surface where the temperature is  $\mathrm{}\mathrm{}25°C$ and the pressure is 1.0 bar, what will happen to the volume of the bubble?

The correct value of the gas constant is close to:

what is boyle's law?

A gas is filled in a vessel of volume $\mathrm{V}$ at ${35}^{\circ }\mathrm{C}$. To what temperature should it be heated in order that half of the gas may escape out ?

Internal energy of $n_1$ mol of hydrogen of temperature $T$ is equal to the internal energy of $n_2$ mol of helium at temperature $2T$. The value of $\frac{10n_1}{n_2}$ is

At STP, $5.6$ litre of a gas weighs $60\mathrm{ }\mathrm{g}$. The vapour density of gas is -

The below graph represents Gay-Lussac’s law.

Explain graphical representation of Gay-Lussac’s law.

State the Gay-Lussac's law graphically.

The slope of Gay-Lussac's law is 

The graph between P and T according to Gay lussac's law is a

From a certain apparatus, the diffusion rate of hydrogen has an average value of $28.7 \mathrm{c}{\mathrm{m}}^3\mathrm{ }{\mathrm{s}}^{-1}$. The diffusion of another gas under the same conditions is measured to have an average rate of $7.2 {\mathrm{cm}}^3{\mathrm{s}}^{-1}$. Identify the gas.

What should be the percentage increase in pressure for a $5\%$ decrease in volume of a gas at constant temperature? 

Boyle's law states that the volume of an ideal gas is directly proportional to the absolute temperature at constant pressure.

At STP, 5.6 litre of a gas weighs $60\mathrm{ }\mathrm{g}$. The vapour density of gas is -

For comparing the same substance under different sets of conditions, Avogadro's law can be expressed as:

Explain why the number of atoms in a certain volume of hydrogen is twice the number of atoms in the same volume of helium at the same temperature and pressure.

A gas is heated from $273 \mathrm{K}$ to $373 \mathrm{K}$ at $1 \mathrm{atm}$ pressure. If the initial volume of the gas is $10 \mathrm{L}$, its final volume would be

Air expands on heating and hence its density _____. (increases/ decreases)
