Why can't water be heated up above 90 degrees?
Because when it reaches that temperature, the water that is hotter than 90 degrees evaporates as a gas.

Explain on a particle level what happens when a solid melts.
The vibrations of the solid are strong enough to disrupt the crystal lattice and break the intermolecular forces holding the molecules together.

What is Boyle's Law?
For a fixed mass of gas at constant temperature, the volume of the gas varies inversely with pressure.

Explain why ionic compounds are very good conductors of electricity when they are melted or dissolved in a liquid.
When ionics dissolve or melt they can break into their corresponding ions. These positive and negatively charged species allow electricity to pass through the liquid.
