Atmospheric pressure
Definition
The pressure exerted by the atmosphere
Term
Avogadro's law
Definition
A gas law that states that the volume of gas is directly related to the number of moles of gas in the sample when pressure and temperature do not change
Term
Boyle's law
Definition
A gas law stating that the pressure of a gas is inversely related to the volume when temperature and moles of the gas do not change
Term
Charles's law
Definition
A gas law stating that the volume of a gas changes directly with a change in Kelvin temperature when pressure and moles of the gas do not change
Term
Combined gas law
Definition
A relationship that combines several gas laws relating pressure, volume, and temperature when the amount of gas does not change
Term
Dalton's law
Definition
A gas law stating that the total pressure exerted by a mixture of gases in a container is the sum of the partial pressures that each gas would exert alone
Term
Direct relationship
Definition
A relationship in which two properties increase or decrease together
Term
