Dalton's Law (words)
The total pressure exerted by the mixture of non-reactive gases is equal to the sum of the partial pressures of individual gases.
Graham's Law (words)
The rate of effusion of a gas is inversely proportional to the square root of the mass of its particles.
A fluid is a substance that continually deforms (flows) under an applied shear stress. Fluids are a subset of the phases of matter and include liquids, gases, plasmas and, to some extent, plastic solids.
In Chemistry, the term diffusion is defined as the movement of particles of a fluid from a place of relatively high concentration to a place with low concentration. It occurs due to the randomness of motion caused by thermal energy.
When there is a barrier with one or many small holes that prevent a gas to expand into the new volume unless a gas molecule happens to travel through the hole. The term "small" when referring to the holes are holes with diameters less than the mean free path of the gas molecules.
Mean Free Path
The average distance traveled by an individual gas molecule before it collides with another gas molecule.
where p is the partial pressure of the solute in the gas above the solution, c is the concentration of the solute and k sub-H is a constant with the dimensions of pressure divided by concentration. The constant, known as the Henry's law constant, depends on the solute, the solvent and the temperature.
The number of moles of a component of a solution divided by the total number of moles of all components.
