At $740 \ torr$ pressure,the volume of $N_2$ gas is $800 \ mL$. If the volume becomes $540 \ mL$ at constant temperature,calculate the pressure of the gas. (in $torr$)

$A$ truck carrying an oxygen cylinder is coming from $Place \, A$. At $Place \, A$,the gas in the cylinder is at a temperature of $-23 \, ^oC$ and a pressure of $3 \, atm$. When the truck passes through $Place \, B$,the temperature is $30 \, ^oC$. What will be the pressure of the oxygen gas in $atm$?

$A$ gas obeys Charles's law in the temperature range $0-500 \ K$ at a given pressure. Its volume changes to zero at a temperature of:

The value of the gas constant $R$ depends on which of the following?

Match the following graphs of a gas with their corresponding $y$ and $x$ coordinates:

Graph	Coordinates ($y$ vs $x$)
$(A)$ Hyperbola	$1. \ y = PV, x = V$
$(B)$ Straight line passing through origin	$2. \ y = P, x = V$
$(C)$ Horizontal line parallel to $x$-axis	$3. \ y = P, x = 1/V$

What is the relationship between the molecular mass,density,and volume of a gas?
