Holt Chemistry Chapter 12: Gases

Robert Boyle

________ discovered the gas pressure of a gas increased, the volume decreased but the product remained constant.

Diffusion

________ causes an increase in entropy.

kinetic molecular theory

The ________ is used to predict gas behavior and states.

average kinetic energy

The ________ is proportional to the temperature in kelvin.

Effusion

________ is the passage of gas through a small opening.

unit of pressure

The ________ is called a pascal.

Pressure

________ exerted is a result of collisions of molecules against the container.

PV

________= nRT where R is constant.

T

________= temperature of the gas in kelvin.

Thomas Graham

________ discovered that the rate of effusion is inversely proportional to the square root of the gass molar mass (M)

Air pressure

________ is the collision of gas molecules.

ideal gas

The ________ is imaginary and has particles that are infinitely small and do not interact with one another.

ratio of gas volumes

The ________ is the same as the ratio of moles in a balanced equation.

Gases

________ are unique because the distance between particles is greater than the distances in liquids and solids.

unit of force

The ________ is called a Newton.

Gas particles

________ are in constant rapid, random motion.

Diffusion

________ is the movement of particles from regions of high density to areas of lower density.

Pressure

________ is forced divided by area, meaning the amount of force exerted per surface area unit.

Gases

________ are considered fluids because they can flow.

Gases

________ are very compressible because the total space the particles take up is much smaller than the total volume.
