If we froze water, what physical properties would change? What would stay the same?
The molecules would change their structure (arrangement). It leads to an increase in volume and a decrease in density. By the water molecule at freezing, the ice will float on top of the liquid water.

What affect does adding energy have on a solid? Explain what happens to both the entire solid and the particles that make it up.
Adding energy to a solid causes the particles to move faster. When the particles move faster, the solid structure starts to break apart and a liquid is formed.

What is the difference between kinetic & potential energy?
Potential energy is stored while kinetic energy is in motion.
