Summary

Dalton's law states that the total pressure of a gas is the sum of the individual pressures of all the gas molecules in the container. In other words, it's the average pressure exerted by all the gas particles in a given system. This law is fundamental in determining the behavior of gasses under different conditions, such as changes in temperature or volume.
