5.7 Understand the changes that occur when a solid melts to form a liquid, and when a liquid evaporates or boils to form a gas

Solid to liquid

• More energy
• Particles move faster
• Bump more frequently
• Further apart
• Brush past each other

Liquid to gas

• Much more energy
• Particles move much faster
• Bump more frequently
• Very far apart
• Hardly touch (except when bumping..tee hee)

*mind blown*
