________- how closely packed matter is in a given volume.

________ are traveling in straight- line paths and are randomly distributed.

________- no structure, but touching, non- compressible.

________ is the average measure of kinetic energy.

________- absolute zero (no zeros)

Can be liquified at ________ and high pressures.

________ are actually kilocalories.

A liquid will boil when its ________ equals the pressure of the liquid above it.

________ has a greater influence on boiling than temperature.

energy of the motion of particles

absolute zero (no zeros)

K= c + 273

Absorb heat

release heat

q=mHf

q=mHv

q=mCAT

1 atm or 101.3 kPa or 760 torr

0 C or 273 K

V1/T1 = V2/T2

(P1)(V1)/T1 = (P2)(V2)/T2

Follows all rules above for gas

gas molecules do have a volume and weak attractive forces

Solid to gas

Solids, liquids, and gasses

Crystalline structure, non-compressible

no structure, but touching, non-compressible

No structure, spread out, compressible.

Properties that can be used to identify the substance(element)

point when a solid becomes a liquid

point when a liquid becomes a gas

point when a liquid becomes a solid

how closely packed matter is in a given volume

refers to the space a specific element occupies.

stored energy

energy of the motion of particles

the average measure of kinetic energy

Absolute zero (No zeros)

absorb heat

release heat

energy for heat of fusion for water

energy for heat of vaporization for water

energy for specific heat capacity of water

equation for heat of fusion

equation for heat of vaporization

equation for specific heat capacity

liquid to gas/ gas to liquid

Solid to liquid/ liquid to solid

change in temp, but not phase.

Particles are traveling in straight-line paths and are randomly distributed, No definite shape or volume, Large distances between particles, low densities, Can be compressed, Can be liquified at low temperatures and high pressures.

standard temperature and pressure

1 atm or 101.3 kPa or 760 torr

0 C or 273 K

relationship between pressure and volume (says that the volume occupied by a gas is inversely proportional to the pressure exerted on the gas)

Describes the relationship between volume and temperature (Says that the volume occupied by a gas is directly proportional to the temperature(in kelvin))

Kinetic Molecular Theory

gases move in a random, constant, straight line motion, Have negligible volume, no attraction between particles, If gas molecules do collide no energy is lost or gained.

Follows rules from KMT

gas molecules do have a volume and weak attractive forces

when there is a high temp and low pressure

The pressure that vapor exerts when the temperature of a liquid increases.

the heat required to increase the temperature of a substance by 1 degree

The two elements which are liquid at room temp

The two elements that sublimate at STP

Solid to gas/ gas to solid

when volume increases
