Looking back

Quick recall before we meet the opposite kind of change.

Think back

What is a reversible change?
In a reversible change, does the substance change?
How could you get the sugar back out of sugary water?

Today's question

"When something changes, can we always change it back?"

Today: the changes where the answer is no.

The big test today: has a new substance been made? If yes → irreversible.
