when gases are collected by water displacement, Dalton's law of Partial Pressure can be used to determine the pressure of the gas.

Gas collected by water displacement is never pure but mixed with water vapor

P = P + P

Kinetic Molecular Theory of Gases

5 assumptions of the K-M theory

1. Gases consist of large numbers of tiny particles that are far apart relative to their size

2. Collisions between gas particles and between particles and container walls are elastic collisions.

3. Gas particles are in continuous, rapid, random motion. They therefore possess kinetic energy, which is energy of motion.

4. There are no forces of attraction or repulsion between gas particles

5. The average kinetic energy of gas particles depends on the temperature of the gas.

States that the volume of a fixed mass of gas varies inversely with the pressure at constant temperature

The combined gas law expresses the relationship between pressure, volume and temperature of a fixed amount of gas.

States that equal volumes of gases at the same temperature and presure contain equal numbers of molecules (moles).

The ideal gas law is the mathematical relationship among pressure, volume, temperature, and the number of moles of a gas.
