Physics-Heat and Heat Transfer

Condensation

Gas changing into a liquid due to heat loss

Heat

Energy transfer between substances from temperature difference

Temperature

Measure of average kinetic energy indicating hotness or coldness

Force

Interaction changing object motion, affecting velocity

Convection

Heat transfer by fluid movement from high to low temperature

Conductors

Materials allowing easy passage of heat or electricity

Conduction

Heat transfer between substances in direct contact

Radiation

Emission of energy as electromagnetic waves or particles

Insulators

Materials impeding heat or electricity flow

Solid

State of matter with definite shape and volume, particles vibrate

Liquid

State with definite volume but no shape, particles flow

Gas

State with no definite shape or volume, particles move freely

Plasma

State like gas with electrically charged particles, found in stars
