Phase Changes

How are solids different from liquids?

• particles in solids are moving freely around each other.
• particles in solids have no motion.
• particles in solids are vibrating in place.
• particles in solids have more motion than in liquids

What is the phase change of a solid to a liquid?

• freezing
• melting
• boiling
• condensation

Why is the boiling point in Utah below 212 Fahrenheit?

• Because we have hard water (minerals in the water)
• Because water always boils at 100 degrees Celsius.
• Because Utah is located above sea level (lower atmospheric pressure)
• Because our water is cleaner than water in California

Phase change from a solid to a gas.

• sublimation
• deposition
• condensation
• evaporation
