Thermal & Light Energy Transfer

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object to another, typically occurring from warmer objects to colder ones.

Front

What happens to molecules in a solid?

Back

Molecules in a solid are closely packed together and vibrate in place, maintaining a fixed shape.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion, which increases as the speed of an object increases.

Front

What happens to molecules as temperature increases?

Back

As temperature increases, molecules move faster due to increased kinetic energy.

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object, related to temperature.

Front

What is conduction?

Back

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

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as sunlight.

Front

What is the difference between thermal energy and temperature?

Back

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

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a pot of boiling water.
