Charles's Law doesn't have a specific symbol. It's a gas law that describes the relationship between the volume and temperature of a gas at constant pressure.
Here's how it's usually expressed:
- V₁/T₁ = V₂/T₂
Where:
- V₁ is the initial volume of the gas
- T₁ is the initial temperature of the gas
- V₂ is the final volume of the gas
- T₂ is the final temperature of the gas
This formula helps us understand that the volume of a gas is directly proportional to its absolute temperature when pressure is constant.
Example: If you increase the temperature of a gas, its volume will also increase proportionally.
Practical insights:
- Charles's Law is used in various applications like hot air balloons, weather forecasting, and designing engines.
- It helps explain how gases expand when heated and contract when cooled.
