Here’s a explanation of Gay-Lussac’s Law:
Gay-Lussac’s Law states that:
At constant volume, the pressure of a given mass of gas is directly proportional to its absolute temperature (in Kelvin).
In simpler terms:
- If the temperature increases, the pressure increases.
- If the temperature decreases, the pressure decreases, as long as the volume stays the same.
Key Points:
- Volume must remain constant.
- Temperature must be in Kelvin.
- This law explains why a sealed can may burst when heated—the gas pressure inside rises with temperature.
Example:
- Heating a pressure cooker increases the pressure inside because the water vapor’s temperature rises, while the volume of the cooker remains constant.
