Front

What is a chemical change?

Back

A chemical change is a process where a new substance is formed, such as frying an egg.

Front

What is a physical change?

Back

A physical change is a change that does not alter the chemical composition of a substance, such as melting ice.

How can you speed up the dissolving of syrup in milk?

Back

You can warm up the syrup before putting it into the milk.

Front

What part of the solute does the solvent interact with?

Back

The solvent only interacts with the surface of the solute.

Front

What defines saturated, unsaturated, and supersaturated solutions?

Back

They are defined by how much solute can dissolve in a solvent.

Front

What happens when you stir sugar and water 30 times per minute compared to 10 times per minute?

Back

Stirring sugar and water 30 times per minute will dissolve the sugar faster.

Front

What is a solute?

Back

A solute is a substance that is dissolved in a solvent.

Front

What is a solvent?

Back

A solvent is a substance that dissolves a solute, forming a solution.

Front

What is an example of a saturated solution?

Back

A saturated solution is one where no more solute can dissolve, like sugar in water when it no longer dissolves.

Front

What is an example of an unsaturated solution?

Back

An unsaturated solution is one where more solute can still dissolve, like adding more sugar to water that still dissolves.
