the energy transfer flows in the opposite direction, then you would read the graph in the opposite direction also.

What would be the name of the phase change happening at line b?

• Condensation

• Vaporization

• Sublimation

• Freezing

What type of intermolecular force is primarily responsible for the high boiling point of water?

• Ionic bond

• Covalent bond

• Hydrogen bond

• Metallic bond
