What is the density of $CO_2$ at $100\,^oC$ and $800\,mm\,Hg$ pressure in $g/L$?

When an ideal gas undergoes unrestrained expansion,no cooling occurs because the molecules

For $1 \ mol$ of an ideal gas,an isochore is obtained. The slope of the isochore is $0.082 \ atm \ K^{-1}$. What will be its pressure (in $atm$) when the temperature is $12.2 \ K$? $(R = 0.082 \ L \ atm \ mol^{-1} \ K^{-1})$.

If the absolute temperature of an ideal gas becomes double and the pressure becomes half,the volume of the gas would be:

The density of air is higher at sea level. This fact is a practical application of which law?

$A$ plot of volume $(V)$ of the gas versus temperature ($T$ in $K$) is shown below. Which of the following options is correct for the plot?
