Freezing point

• The classification of matter as a solid, a liquid, or a gas

• Physical change in matter from a gas to a liquid

• The temperature at which a substance changes states from a solid to a liquid

• The temperature at which a substance changes from a liquid to a solid

A student observed a liquid that boiled at 100°C. What type of liquid was boiling?

• Salt water

• Sugar water

• Pure water

• Lemon water

A student is trying to determine if a clear substance is water. The student should measure the substance's -

• Volume

• Solubility

• Mass

• Boiling Point

The temperature at which a substance changes states from a solid to a liquid

• Freezing point

• Melting point

• Evaporation

• Condensation

If water is left to boil, what statement is not true?

• All the water will eventually evaporate.

• The temperature of the water will eventually reach 200°C.

• The temperature of the water will remain at 100°C until it evaporates.

• The beaker with only 100 mL of water will boil away faster than the beaker with 200 mL of water.

What is happening at the boiling point?

• liquid to gas
• gas to liquid
• solid to liquid
• liquid to solid

How can you describe matter?

• properties
• traits
• characterisctics
• how, when, what, and who

Do all matter have the same boiling, melting, and freezing points

• Yes
• No
