Question 1Change answer

Temporary changes happen when materials change, but you can get back what you started with.

Sometimes there is a temporary change when there is a change of state, e.g., melted wax goes back to solid wax when it cools.

Sometimes there is a temporary change when materials are mixed, e.g., when you mix salt and water, they don't form a new substance so you can separate them again.

Give two examples of temporary changes that happen in the kitchen.
