Back

The temperature at which a liquid boils under standard atmospheric pressure.

Front

Heating/Cooling Curve

Back

A graph that shows the change in temperature of a substance as heat is added or removed.

Front

Normal Freezing Point

Back

The temperature at which a liquid turns into a solid under standard atmospheric pressure.

Front

Intramolecular Forces

Back

Forces that hold atoms together within a molecule.

Front

Molar Heat

Back

The amount of heat required to change the temperature of one mole of a substance by one degree Celsius.

Front

Fusion

Back

The process of combining two or more entities to form a new entity, often used to describe the melting of a solid.

Front

Molar Heat of Vaporization

Back

The amount of heat required to vaporize one mole of a liquid at its boiling point under standard pressure.
