Dalton's law states that:
a. The total pressure of a gas mixture equals the sum of the partial pressure of each constituent gas in the mixture.
b. The pressure within a liquid sphere is in-fluenced by the surface tension forces of the liquid and the size of the sphere.
c. There is a direct relationship between the absolute pressure of a gas and its temper-ature.
d. The volume of a gas is inversely related to its pressure.
ANS: A
Dalton's law states that the sum of the partial pressures of a gas mixture equals the total pressure of the system. Laplace's law states that the pressure within a liquid sphere is influenced by the surface tension forces of the liquid and the size of the sphere. Gay-Lussac demonstrated that if the volume of a gas is held constant, the gas pressure rises as the absolute temperature of the gas increases. Boyle's law states that when the temperature is held constant, the volume that a gas occupies is inversely proportional to the absolute pressure exerted on it.
