Which state of matter has a definite shape?

• Gas
• Solid
• Liquid
• Plasma

explanation of the behavior of particles in gases; states that matter is made of constantly moving particles that collide without losing energy

• kinetic theory

• plasma

• sublimation

• thermal expansion

temperature at which a solid begins to liquefy

• melting point

• boiling point

• heat of vaporization

• heat of fusion

the process of a solid changing directly to a vapor without forming a liquid

• sublimation

• pressure

• buoyancy

• viscosity

increase in the volume of a substance when the temperature is increased

• thermal expansion

• Boyle's Law

• Charles's Law

• kinetic theory

Evaporation is

• Gas changing to a liquid
• Solid changing to a liquid
• Liquid changing to a solid
• Liquid changing to a gas
