Front

What is a supersaturated solution?

Back

A solution that contains more solute than it can theoretically hold at a given temperature.

Front

Explain the term 'polar molecule'.

Back

A molecule with a partial positive charge on one side and a partial negative charge on the other, allowing it to interact with other polar substances.

Front

What is the significance of water's high specific heat?

Back

It helps regulate temperature in the environment and in living organisms.

Front

Define solubility.

Back
