Gases

What do each letter in the ideal gas law stand for?

Under ideal conditions, pressure and volume are

• always equal.

• directly proportional.

• indirectly proportional.

Why do we need the correction for the volume of the gas?

• Molecules are interacting with one another and "sticking" together.

• Real gas particles occupy some of the volume of the container.

• The volume of the container is measured from the outside so we have to correct for the walls of the container.

How are the values of a and b determined?

• They are based on the molar mass

• From number of protons, neutrons, and/or electrons.

• From experimental data

• From number of atoms in each gas particle.
