According to Charles’ Law, volume and temperature are directly related. This means that __________.

Understanding Charles' Law

Charles' Law states that the volume (V) of a gas is directly proportional to its absolute temperature (T) when the pressure is held constant. This relationship can be mathematically expressed as follows:

$V \propto T$ or in equation form: $\frac{V_1}{T_1} = \frac{V_2}{T_2}$

Implication of Direct Relationship

1. Direct Relationship: When the temperature of a gas increases, its volume increases, provided that the pressure remains constant. This is because increasing the temperature increases the kinetic energy of the gas molecules, causing them to move apart and occupy a larger volume.

2. When Temperature Decreases: Conversely, if the temperature of the gas decreases, its volume also decreases under the same constant pressure conditions.

3. Practical Applications: This principle can be observed in everyday scenarios, such as when a balloon is heated and expands, or when it cools down and contracts.

Final Answer

This means that as the temperature of a gas increases, its volume also increases, and vice versa, when pressure is kept constant.
