Heat Transfer and Energy - Science Test

Flashcards covering key concepts related to heat transfer and energy for the science test.

Thermal Energy

Total kinetic energy of particles in a substance.

Heat Energy

The transfer of thermal energy from a hotter object to a colder object.

Conduction

Heat transfer through direct contact between particles.

Example of Conduction

Touching a metal spoon sitting in hot soup.

Convection

Heat transfer through fluids (liquids or gases) by the movement of the fluid itself.

Example of Convection

Boiling water - hot water rises, cooler water sinks.

Radiation

Heat transfer through electromagnetic waves, without needing matter.

Example of Radiation

Feeling heat from the Sun on your skin.

Conductor

A material that allows heat to move through it easily.

Examples of Conductors

Metals like copper and aluminum.

Insulator

A material that slows down or blocks heat transfer.

Examples of Insulators

Rubber, wood, plastic, and air.

Trick to remember Conduction

Conduction = Contact (both start with C!)

Trick to remember Convection

Convection = Currents (moving fluids).

Trick to remember Radiation

Radiation = Rays (energy moves in rays, like sunlight).
