TEKS 7.8 A, B, & C

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when particles collide and transfer energy.

Front

Give an example of conduction.

Back

Placing ice into a glass of water to chill it.

Front

What is temperature?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in a substance, including both kinetic and potential energy.

Front

True or False: A swimming pool at 30°C has more thermal energy than a cup of soup at 60°C.

Back

True.

Front

What type of energy transfer occurs in a microwave oven?

Back

Radiation.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as light or heat.

Front

Give an example of thermal energy transfer by radiation.

Back

Sun bathing.

Front

What is convection?

Back

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

Front

Give an example of convection.

Back

Cool water sinking down through the ocean.
