Here’s a explanation of Charles’s Law:
Charles’s Law states that:
At constant pressure, the volume of a given mass of gas is directly proportional to its absolute temperature (measured in Kelvin).
In simpler terms:
- When temperature increases, volume increases.
- When temperature decreases, volume decreases, as long as the pressure stays the same.
Key Points:
- Temperature must be in Kelvin.
- Pressure must remain constant.
- It explains why gases expand when heated and contract when cooled.
Example:
- A hot-air balloon rises because heating the air increases its volume.
- A balloon shrinks when placed in a freezer because the gas volume decreases.
