Question | Answer |
---|---|
Diffusion | Spontaneous mixing of the particles of two substances caused by their random motion |
Effusion | A process by which gas particles under pressure pass through a tiny opening |
Elastic Collision | A collision between gas particles and between gas particles and container walls in which there is no net loss of kinetic energy |
Fluid | A substance that can flow and therefore take the shape of its container; a liquid or gas |
Ideal Gas | An imaginary gas that perfectly fits all the assumptions of the kinetic-molecular theory |
Kinetic-Molecular Theory | A theory based on the idea that particles of matter are always in motion |
Real Gas | A gas that does not behave completely according to the assumptions of the kinetic-molecular theory |
Atmosphere of Pressure | Exactly equivalent to 760 mmHg |
Barometer | A device used to measure atmospheric pressure |
Millimeter of Mercury | A common unit of pressure |
Newton | The SI unit for force; the force that will increase the speed of a one kilogram mass by one meter per second each second it is applied |
Pascal | The pressure exerted by a force of one newton acting on an area of one square meter |
Pressure | The force per unit area on a surface |
Standard Temperature and Pressure | The agreed-upon standard conditions of exactly 1 atm pressure and 0 degrees C |
Absolute Zero | The temperature -273.15 degrees C, given a value of zero in the Kelvin scale |
Boyle's Law | The volume of a fixed mass of gas varies inversely with pressure at constant temperature |
Charles's Law | The volume of a fixed mass of gas at constant pressure varies directly with the Kelvin temperature |
Combined Gas Law | The relationship between the pressure, volume, and temperature of a fixed amount of gas |
Dalton's Law of Partial Pressures | The total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases |
Gas Laws | Simple mathematical relationships between the volume, temperature, pressure, and quantity of a gas |
Gay-Lussac's Law | The pressure of a fixed mass of gas at constant volume varies directly with the Kelvin temperature |
Partial Pressure | the pressure of each gas in a mixture |
