Dalton's Law, Charles and Boyle's Law

Pressure in gases is a measure of:

• the number of collisions per second of the particles with the side of the container.

• the force of the collisions of the particles with the side of the container.

• the amount of space taken up by the particles in the container.

• None of the above
