Thermal Energy

thermal insulator

a material through which thermal energy does not flow easily.

thermal conductor

a material through which thermal energy flows easily. these electrons transfer kinetic energy when they collied with other electrons and atoms.

convection

convectiond only occurs in fluids such as water,air,magma, and maple syrup. convection is the transfer of thermal energy by the movement of particles.

radiation

the transfer of thermal energy from one material to another by electromagnetic waves is called radiation. radiation is the only way thermal energy can travel from the sun to earth becouse space is a vacuum.

conduction

the transfer thermal energy between materials by the collisions of particles is called conduction. conduction continues untill the thermal energy of all particles that are in contact is equal.

thermal insulator

thermal insulator is a material through which thermal energy does not flow easily. the electrons in the atoms of a good thermal insulator do not move easily.
