If the density of neon gas at $350 \ K$ is $0.9 \ g \ L^{-1}$,calculate the pressure of the gas. (in $bar$)

Calculate the new pressure of a gas enclosed in a cylinder when it is compressed from $5 \text{ L}$ to $2 \text{ L}$ at an initial pressure of $1 \text{ atm}$ and temperature of $300 \text{ K}$. The final temperature in this process is $500 \text{ K}$. (in $\text{ atm}$)

One litre of a gas weighs $2 \ g$ at $300 \ K$ and $1 \ atm$ pressure. If the pressure is made $0.75 \ atm$,at which of the following temperatures will one litre of the same gas weigh $1 \ g$?

Use of hot air balloons in sports and meteorological observations is an application of

$A$ gas at $5 \, bar$ pressure is heated from $0 \, ^\circ C$ to $546 \, ^\circ C$ and its volume is reduced to one-third of its initial volume. Calculate the final pressure. (in $, bar$)

At a given temperature,the density of an ideal gas is proportional to $(P = \text{pressure of ideal gas})$
