Solids, Liquids, and Gases- Changes in State

Why is the volume of a solid considered definite?

• The particles in a solid are far apart

• The particles in a solid are tightly packed

• The particles in a solid move very quickly

• The particles in a solid exhibit absolutely no movement

The kinetic theory states

• Particles won't move if you don't apply energy to it.

• Particles are always in motion.

• Particles only move in liquids and gases.

• At the same temperature the object that has the most mass heats quicker.

This state of matter would have the least amount of kinetic energy and the strongest force of attraction.

• Gas

• Solid

• Liquid

• Plasma

When heat is added, particles in a solid, liquid or gas...

• Are not affected

• Move slower

• Move faster

• None of the above
