Imagine you are making a cup of tea. What would you describe as a solute?

• The water, which is present in the largest amount

• The tea leaves, which get dissolved

• The water, which is the solvent

• The water, which surrounds and breaks apart the tea leaves

How does a solution become supersaturated?

• dissolve lots of solute in it.

• dissolve a little solute in it.

• dissolve more solute than normal by adding heat

• dissolve a super amount of solvent in it.
