The mass of an ice cube in a closed container is measured on a triple beam balance. The ice cube is then melted in the same closed container and the mass of the liquid water is measured. Will the mass of the liquid water be more, less, or the same as the ice cube?
The same. (Conservation of Mass!)

Describe how the particles/molecules in each of the 3 states of matter are arranged.
Solid- Tightly packed, organized pattern Liquid- Tightly packed but can move freely, no pattern Gas- Spread apart. Move around freely

Describe how potential energy changes into kinetic energy, and back into potential energy in a roller coaster.
When the coaster is moving slowly at the top of a hill, it has potential energy. When it starts falling down a hill and gaining speed, it is gaining kinetic energy. When it loses speed and climbs another hill, it is gaining potential energy.
