What do these two changes have in common?
water freezing into ice
peeling a banana
Both are caused by cooling. Both are chemical changes. Both are only physical changes. Both are caused by heating.
Step 1: Think about each change.
Water freezing into ice is a change of state. So, it is a physical change. The water changes from solid to liquid. But the ice is still made of the same type of matter as the liquid water.
Peeling a banana is a physical change. The peel is not covering the rest of the fruit anymore. But both the peel and the banana are still made of the same type of matter as before.
Step 2: Look at each answer choice.
Both are only physical changes.
Both changes are physical changes. No new matter is created.
Both are chemical changes.
Both changes are physical changes. They are not chemical changes.
Both are caused by heating.
Neither change is caused by heating.
Both are caused by cooling.
Water freezing is caused by cooling. But peeling a banana is not.
