The equation for an ideal gas is $PV = RT,$ where $V$ represents the volume of

Air pressure in a car tyre increases during driving. Explain.

State Gay-Lussac's Law.

At a temperature $T \ K$,the pressure of $4.0 \ g$ argon in a bulb is $p$. The bulb is put in a bath having a temperature higher by $50 \ K$ than the first one. $0.8 \ g$ of argon gas had to be removed to maintain the original pressure. The temperature $T$ is equal to ..... $K$.

The number of molecules in a gas at pressure $1.64 \times 10^{-3} \text{ atm}$ and temperature $200 \text{ K}$ having the volume $1 \text{ cc}$ is:

What is $1$ mole? Write two different methods to represent a mole.
