Abstract

Boyle's law: The volume of a given mass of gas, at constant temperature, is inversely proportional to its pressure. Dalton's law: The pressure of a mixture of gases is equal to the sum of the partial pressures of its constituents. Charles's law (Gay-Lussac's law): The volume of a given mass of gas, at constant pressure, increases by 1/273 of its value at 0°C, for every degree Centigrade rise in temperature. Henry's law: The amount of gas dissolved in a solution is directly proportional to the pressure of that gas over the solution. Law of gas diffusion: Gas molecules will diffuse from an area of higher concentration to an area of lower concentration until equilibrium is reached. Graham's law: The rate of diffusion of a gas is inversely proportional to the square of its density. Convection and forced convection: The transfer of heat in a gas or liquid is proportional to temperature difference and can be increased by increasing airflow. —Nelkon and Parker, 1962
