Term | Definition |
---|---|
Boyle's Law | For a given mass of gas at constant temperature, the volume of the gas caries inversely with pressure |
Charle's Law | The volume of a fixed mass of gas is directly proportional to its Kelvin temperature if the pressure is kept constant |
Combined Gas Law | The law that describes the relationship among the pressure, temperature of an enclosed gas |
Compressibility | A measure of how much the volume of matter decreases under pressure |
Dalton's Law of Partial Pressures | At constant volume and temperature, the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures of the component gases |
Diffusion | The tendency of molecules to move toward areas of lower concentration until the concentration is uniform throughout |
Effusion | The process that occurs when a gas escapes through a tiny hole in its container |
Gay-Lussac's Law | The pressure of a gas is directly proportional to the kelvin temperature if the volume is constant |
Graham's Law of Effusion | The rate of effusion of a gas is inversely proportional to the square root of its molar mass |
Ideal Gas Constant | The constant in the ideal gas law with the symbol R and the value 8.31 (L*kPa)/ (K*mol) |
Ideal Gas Law | The relationship PV=nRT, which describes the behavior of an ideal gas |
Partial Pressure | The contribution each gas in a mixture of gases makes to the total pressure |
Kinetic Theory | A theory explaining the states of matter, based on the concept that all matter consists of tiny particles that are in constant motion |
