6.7ABC Thermal Energy Transfer CCA

Front

What is thermal energy?

Back

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

Front

How does temperature relate to the movement of molecules?

Back

Temperature is a measure of the average kinetic energy of the molecules in a substance; higher temperatures mean faster-moving molecules.

Front

What happens to the particles of a gas compared to those in a liquid or solid?

Back

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

Front

What determines the temperature of a substance?

Back

The speed of the molecules determines the temperature of a substance.

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) caused by differences in temperature.

Front

What is radiation?

Back

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

Front

What is the design problem related to high-temperature handles on cookware?

Back

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

Front

What is the role of heat in thermal energy transfer?

Back

Heat is the energy that is transferred from one object to another due to a temperature difference.

Front

What is the difference between thermal energy and temperature?

Back

Thermal energy is the total energy of all the particles in a substance, while temperature is a measure of the average kinetic energy of those particles.
