8th Grade CUA 1 - Unit 3 (Module1) Energy and Matter

Front

What is the effect of type of matter on temperature change?

Back

Different materials heat up at different rates when the same amount of energy is added. For example, metals like copper heat up faster than wood.

Front

What device is designed to maximize thermal energy transfer?

Back

A frying pan is designed to conduct heat efficiently, allowing for quick cooking.

Front

What is thermal energy transfer by conduction?

Back

Conduction is the transfer of heat through direct contact. For example, a metal spoon getting hot in boiling water.

Front

What is temperature?

Back

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

Front

What is a criterion in design?

Back

A criterion is a standard or principle by which something is judged or decided. For example, a water filter must remove at least 90% of impurities.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to temperature.

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) due to differences in density.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as heat from the Sun.

Front

What is specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of 1 kg of a substance by 1 degree Celsius.
