Part I—Matching
Match the following gas laws to the descriptions and the formulas that
follow. Answers can and will be used more than once.
a. Boyle's Law
c. Dalton's Law
e. Ideal Gas Law
b. Charles's Law
d. Graham's Law
_____1. This law states that the volume of a gas at constant pressure
varies directly with its Kelvin temperature.
_____2. This law states that under equal conditions of temperature and
pressure, gases diffuse at a rate that is inversely proportional to
the square roots of their molecular masses.
_____3. This law states that the total pressure exerted by a mixture of
gases is equal to the sum of each of the partial pressures of the
gases in the mixture.
_____4. This law states that the pressure and volume of a gas at constant
temperature are inversely proportional to each other.
_____5. This law shows the relationship between the pressure, volume,
temperature, and number of particles of a gas.
