measure of the force of a collision in a given area

What is volume?

measurement scientist use to determine the amount of space matter takes up

What is Molar volume?

What does the Ideal Gas Law describe?

the physical behavior of an ideal gas in terms of the pressure, volume, temperature, and number of moles of a gas present

What is the Ideal Gas Law Formula?

PV = nRT

What are the R constant value conversions for the Ideal Gas Law Formula?

8.314 (kPa)(L) / (mol)(K) = 62.36 (mmHg)(L) / (mol)(K) = 0.00821 (atm)(L) / (mol)(K)

What is Dalton’s Law?

The total pressure of a mixture of gases is the sum of the partial pressures of the individual gases

What is Graham’s Law of Effusion?

The rate of effusion (or diffusion) of a gas is inversely related to its molar mass

What is Diffusion?

gas molecules spread from high concentration to low concentration.

What is Effusion?

gas molecules ability to pass through a small opening.

Lighter gases spread ____ than heavier gases

faster

What is Graham’s Law of Effusion formula?

Rate of effusion for gas 1/Rate of effusion for gas 2 = √MW2/√MW1
