How does adding thermal energy to water in a liquid state affect the molecules?

• Adding thermal energy to a liquid causes the molecules to break apart form a crystal formation and begin to move.
• Adding thermal energy to a liquid causes the molecules to break apart even more and move at rapidly.
• Adding thermal energy to a liquid causes the molecules to slow down and begin to bond.

What is the definition of the word "properties"?

• molecules that are bonded together
• heat energy applied to molecules
• atoms that are bonded together
• the characteristics (or traits) of something

What is the definition of the term "thermal energy"?

• energy that comes from properties
• energy that comes from molecules
• energy that comes from heat
• energy that comes from hydrogen and oxygen

How does removing thermal energy in a gaseous state affect the molecules?

• Removing thermal energy from a gas causes the molecules to slow down and bond in a crystal formation.
• Removing thermal energy from a gas causes the molecules to move very rapidly.
• Removing thermal energy from a gas causes the molecules to slow down and begin to bond with each other.

Which of the following describes water molecules in the solid state?
