What is more firm?

300

Why do some things float and others sink?

What is pressure and density?

400

The change from a gas into a liquid

What is condensation?

400

This allows a gross spider to float on water as if the water had a thin film

What is surface tension?

400

Temperature and thermal energy are different because?

Thermal energy is the total amount of energy contained in a body whereas temperature measures the average kinetic energy of the particles in the body.
