Isobaric Process

a closed-system process for which the PRESSURE is held constant

Isovolumetric Process

a closed-system process for which the VOLUME is held constant

Isothermal Process

a closed-system process that is held at constant TEMPERATURE

Intensive Properties

Properties that do NOT change based on the scale of the gas being considered (pressure and temperature)

Extensive Properties

Properties that change with scale (volume and number of moles)

Partial Pressure

The contribution each gas makes to the total atmospheric pressure

Diffusion

the tendency of molecules to move toward areas of low concentration until the concentration is uniform

Effusion

A gas escapes through a tiny hole in a container

Saturated Vapor Pressure

maximum pressure of water vapor in air

Dewpoint

the temperature at which air is saturated with water vapor

Relative Humidity

The percent ratio of actual water vapor partial pressure to the saturated vapor pressure

Ideal Gas Law Formula

PV=nRT
