6.7ABC Thermal Energy Transfer CCA

Front

What is thermal energy?

Back

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

Front

What is temperature?

Back

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

Front

How do particles in a gas move compared to those in a liquid or solid?

Back

Particles in a gas move faster than the particles of the same substance in the liquid or solid state.

Front

What is the design problem when a pan's handle is damaged by high temperatures?

Back

The problem is to design pans that have handles that won't be damaged by high temperatures.

Front

What does it mean for thermal energy to flow?

Back

Thermal energy flow refers to the transfer of energy from a hotter object to a cooler object.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids and gases).

Front

What is radiation?

Back

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

Front

What factors affect the rate of thermal energy transfer?

Back

The rate of thermal energy transfer is affected by temperature difference, material properties, and surface area.

Front

What is the relationship between thermal energy and temperature?

Back

As thermal energy increases, the temperature of a substance typically increases, indicating higher average kinetic energy.
