partial pressure
In a mixture of gases, each gas has a partial pressure which is the hypothetical pressure of that gas if it alone occupied the volume of the mixture at the same temperature

partial pressure
In a mixture of gases, each gas has a partial pressure which is the hypothetical pressure of that gas if it alone occupied the volume of the mixture at the same temperature
absolute zero
Absolute zero is the lower limit of the thermodynamic temperature scale, a state at which the enthalpy and entropy of a cooled ideal gas reaches its minimum value, taken as 0
effusion
Effusion is the process in which a gas escapes through a hole of diameter considerably smaller than the mean free path of the molecules
ideal gases
An ideal gas is a theoretical gas composed of many randomly moving point particles that do not interact except when they collide elastically
real gases
Real gases are non-hypothetical gases whose molecules occupy space and have interactions; consequently, they adhere to gas laws
pressure
Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed
