• The amount of heat energy required to raise 1mL of water 1°C

What is polarity?

How does hydrogen bonding act in the gas state?

• Molecules gain enough energy that they move so fast they will break free from H bonding holding them to another molecule.

• Molecules are moving throughout one another and are constantly forming, breaking, and reforming H bonds.

• Molecules are moving very slowly/vibrating in place. Each molecule participates in H bonding with 4 other molecules.

How does hydrogen bonding act in the liquid state?

• Molecules gain enough energy that they move so fast they will break free from H bonding holding them to another molecule.

• Molecules are moving throughout one another and are constantly forming, breaking, and reforming H bonds.

• Molecules are moving very slowly/vibrating in place. Each molecule participates in H bonding with 4 other molecules.

How does hydrogen bonding act in the solid state?

• Molecules gain enough energy that they move so fast they will break free from H bonding holding them to another molecule.

• Molecules are moving throughout one another and are constantly forming, breaking, and reforming H bonds.

• Molecules are moving very slowly/vibrating in place. Each molecule participates in H bonding with 4 other molecules.

what is an ionic bond?

• A bond that forms between two atoms where one gains electrons and one loses electrons.

• A bond between two atoms where they share electrons.
