Front

Define the term 'electromagnetic waves'.

Back

Waves of energy that travel through space and matter, including radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Front

What is convection?

Back

The transfer of heat through the movement of fluids (liquids and gases) due to differences in temperature.

Front

What is the difference between independent and dependent variables in an experiment?

Back

The independent variable is the one that is changed or controlled, while the dependent variable is the one that is measured or affected.

Front

What is the definition of a solid?

Back

A state of matter characterized by structural rigidity and resistance to changes in shape or volume.

Front

Explain why sound travels faster in solids than in gases.

Back

Sound travels faster in solids because the particles are closer together, allowing vibrations to transfer more quickly.
