A gas at

200\,\text{K}

occupies

4.0\,\text{L}

. What volume does it occupy at

400\,\text{K}

(constant pressure)?

1
Charles's Law: $\frac{V_1}{T_1} = \frac{V_2}{T_2}$ . So $V_2 = V_1 \times \frac{T_2}{T_1}$ .
2
$V_2 = 4.0 \times \frac{400}{200} = 8.0\,\text{L}$ .

Answer

V_2 = 8.0\,\text{L}

Charles's Law shows that volume and temperature are directly proportional at constant pressure. Doubling the Kelvin temperature doubles the volume.

About Gas Laws

A set of mathematical relationships that describe how the pressure, volume, temperature, and amount (moles) of a gas are interconnected.

A gas occupies [formula] at [formula]. What is its volume at [formula] (constant temperature)?

Use the ideal gas law to find the volume occupied by [formula] mol of gas at [formula] and [formula]

A gas occupies [formula] L at [formula] atm. If the pressure increases to [formula] atm at constant
