Charles's Law describes the relationship between the volume and temperature of a gas at constant pressure. It states that the volume of a gas is directly proportional to its absolute temperature (measured in Kelvin) when the pressure is held constant.
### Formula
The formula for Charles's Law can be expressed as:
\[
\frac{V_1}{T_1} = \frac{V_2}{T_2}
\]
Where:
- \( V_1 \) = initial volume of the gas
- \( T_1 \) = initial temperature of the gas (in Kelvin)
- \( V_2 \) = final volume of the gas
- \( T_2 \) = final temperature of the gas (in Kelvin)
### Relationship
- As the temperature of a gas increases (at constant pressure), the volume of the gas also increases. This is because the gas particles move more rapidly and require more space.
- Conversely, if the temperature decreases (at constant pressure), the volume of the gas decreases.
### Important Notes
1. **Absolute Temperature**: It's important to use the Kelvin scale when applying Charles's Law because gas laws require absolute temperature to be accurate.
2. **Constant Pressure**: Charles's Law only applies when the pressure remains constant. If pressure varies, other gas laws should be considered, like the Combined Gas Law.
By understanding and applying Charles's Law, you can predict how a gas will behave when its temperature changes under constant pressure conditions.
