IB Physics B.3 Gas Laws Questionbank

The graph shows the variation of pressure $p$ with volume $V$ for a fixed amount of gas. Two curves are shown:

• The dashed line represents gas behavior at temperature $T_1$.
• The solid line represents the same gas at a higher temperature $T_2$.

A sealed container holds a fixed mass of gas at constant temperature. The volume of the gas is reduced from $4.0\ \text{m}^3$ to $2.0\ \text{m}^3$.

An ideal gas is confined in a container with a movable piston at a temperature of $27\text{ }^\circ\text{C}$. If the volume of the gas is doubled while the pressure remains constant, what will be the final temperature of the gas in degrees Celsius ($^\circ\text{C}$)?

If the number of molecules in a sealed container is doubled, what happens to the pressure (assuming constant volume and temperature)?

Two gases are sealed in two identical rigid containers. Gas $A$ has a mass of $m$, pressure $P$ and absolute temperature $T$. Gas has a mass of , pressure , and absolute temperature . What is ?
