One mole of an ideal gas occupies $12 \ L$ at $297^{\circ} C$. What is the pressure of the gas?

Volume of a given mass of gas at $17 \, ^oC$ is measured as $200 \, cm^3$. The volume of the same mass of that gas at same pressure and at temperature of $47 \, ^oC$ will be .............. $cm^{3}$

Explain the relationship between the moles of a gas,its volume,and its density.

$A$ gas cylinder containing cooling gas can withstand a pressure of $14.9 \text{ atm}$. The pressure gauge of the cylinder indicates $12 \text{ atm}$ at $27 \,^oC$. Due to a sudden fire in the building,the temperature starts rising. The temperature at which the cylinder explodes is ............. $^oC$. (in $.5$)

The value of the universal gas constant $R$ is:

If the density ratio of a gas is $1:2$ and the temperature ratio is $2:1$,what will be the ratio of their pressures?
