Charles’s Law


Charle’s Law

Assuming constant pressure, increasing the temperature of the gas will speed up the molecular motion. As the gas often collides with the vessel wall, the volume increases.
Conversely, if you lower the temperature of the gas, the molecular motion will slow down. As the number of collisions of gas decreases, the volume of the gas is also reduced.
As the gas temperature increases at constant pressure, the gas volume increases at a constant rate. At this time, the gas volume change is the same regardless of the type of gas.
