Heat Transfer Flashcard

Front

What is temperature?

Back

Temperature is the measure of the average kinetic energy of the particles in a substance, indicating how hot or cold it is.

Front

What are insulators?

Back

Insulators are materials that slow down or prevent the transfer of heat.

Front

What is conduction?

Back

Conduction is the process of heat transfer through direct contact between materials.

Front

What is convection?

Back

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

Front

What is radiation?

Back

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

Front

What are conductors?

Back

Conductors are materials that easily transfer heat.

Front

How does a microwave oven heat food?

Back

A microwave oven uses radiation to heat food by causing water molecules in the food to vibrate.

Front

What is the relationship between temperature and molecular motion?

Back

As temperature increases, the motion of molecules increases, leading to higher kinetic energy.

What is an example of a good insulator?

Back

An example of a good insulator is rubber or fiberglass.

Front

What is an example of a good conductor?

Back

An example of a good conductor is copper or aluminum.
