What is surface tension?
The result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together, causing the surface to act as if it has a thin skin

A student puts an ice cube on a tray and records the mass. Eventually the cube melts and after 24 hours the student records the mass of what is left. It is less than the original mass. The student concludes that some of the matter that made the ice must have been destroyed. Is this a good explanation for why the recorded masses are different? Explain:
Some probably evaporated. Matter can NOT be created or destroyed.

How does temperature affect solubility?
Increasing temperature increases the rate at which something dissolves.

Describe the particle arrangement their kinetic energy for each state of matter.
Solid: particles are packed close together; kinetic energy is the lowest
Liquid: particles are close together, but can slide past each other; kinetic energy is higher than that of a solid.
Gas: particles are very spread out; particles have the highest kinetic energy
