thermal energy science vocab

Thermal energy

The total energy of all the part iCals (atoms and molecules ) in an object this is related to the objects temperature and mass

Temperature

The measure of the average kinetic energy of the particles in a substance high temperature =fast moving particles

Heat

Thermal energy that is transferred Delma warmer object to a cooler object energy always moves from hoy to cold

Energy transfer

the movement of heat from one place to another there are three main methods conduction, convection from hot to cold

Conduction

The transfer of heat though direct contact between particles eg a spoon gets hot in a bowl of soup occurs best in solids

Convection

The transfer of heat through the movement of fluids liquids or gases hot fluid rises cool fluid sinks, creating a current eg boiling water, warm air in a room

Radiation

The transfer of heat through electromagnetic waves like light no direct contact or matter is needed eg heat from sun or a fire

Conducted

A marterial that allows heat to transfer easily eg metros like copper or aluminum

Insulator

A material that slows down or blocks the transfer of heat eg plastic wood foam air

Property

A feature that describes a material eg high conductivity low density use this word instead of trait
