14.3 Ideal Gases

The volume occupied by a gas at a specified temperature and pressure depends on the number of particles.

• True

• False

The number of moles of gas is ....................... proportional to the number of particles.

• inversely

• directly

An ideal gas is one that doesn't follow the gas laws at all conditions of pressure and temperature

• True

• False

Real gases .................. an ideal gas at low temperatures and high pressures.

• are behaving as same as

• differ most from

When the pressure, volume, and temperature of a contained gas are known, you can use the ideal gas law to calculate the number of moles of the gas.

• True

• False
