Thermal Energy Unit Test

Thermal energy is the total kinetic energy of the particles in a substance, which determines its temperature.

Conduction is the transfer of heat from a hotter object to a colder object through direct contact.

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature.

Radiation is the transfer of heat in the form of electromagnetic waves, such as light or infrared radiation.

A thermometer is a tool used to measure the temperature of a substance.

Darker colors absorb more heat than lighter colors, which reflect more light.

Insulation is used to reduce heat transfer between objects, keeping heat in or out.

Metals like copper and aluminum are good conductors of heat.

Materials like wood, glass, and plastic are good insulators.

When a substance is heated, its particles gain energy and move faster, increasing the temperature.
