Energy Transformations Review

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids or gases). It occurs when warmer, less dense fluid rises and cooler, denser fluid sinks.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves. It does not require a medium and can occur in a vacuum.

Front

What is thermal energy?

Back

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

Front

What is light energy?

Back

Light energy is a form of electromagnetic radiation that is visible to the human eye and can be converted into other forms of energy.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, which can be released during a chemical reaction.

What is an example of conduction in everyday life?

Back

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

Front

What is an example of convection in everyday life?

Back

An example of convection is the way warm air rises and cool air sinks in a room, creating a circulation of air.

Front

What is an example of radiation in everyday life?

Back

An example of radiation is feeling the warmth of the sun on your skin, even when you are not in direct contact with it.

Front

What happens during photosynthesis?

Back

During photosynthesis, plants convert light energy into chemical energy, producing glucose and oxygen from carbon dioxide and water.
