describe the attraction of particles in each of the three states of matter

solid-strong liquid-some attraction gas- no attraction

Describe the kinetic energy in gases, including the collisions

motion is rapid, constant, random, collisions are elastic (no loss of energy)

Atmospheric pressure increases/decreases as you climb in altitude

decreases

Atomospheric pressure de- This is because the _____ of the particle decreases

density

Atmospheric pressure is measured with a

barometer

a measure of a force exerted by a gas above a liquid

vapor pressure

vapor pressure is measured with a

manometer

vapor pressure increase/ decreases as temp increases

increases

bioling point occurs when vapor pressure equals

external pressure on a liquid

explain why the boiling point of a substance decreases as altitude increases

atmospheric/external pressure decrease

2 types of sold

crystalline and amorphous

crystalline solid has a

orderly arrangment

amorphous solids have

no arrangement

the change from a gas directly to a solid

deposition(frost)

change from a solid directly to a gas

sublimation (dry ice)

how much the volume of matter decreases under pressure

compressability

Boyle's law states that volume and pressure are inversely related, which means if volume increases, pressure

decreases

Charles' law states that temperature and volume are directly related, which means if temperature increases, volume

increases

the ___ Gas law states that moles can be calculated if volume, temperature, and pressure are known

Ideal
