What do these two changes have in common? dust settling out of the air a puddle freezing into ice on a cold night

[ "Both are caused by cooling.", "Both are only physical changes.", "Both are chemical changes.", "Both are caused by heating." ]

B

Step 1: Think about each change. Dust settling out of the air is a physical change. As the dust settles, or falls, it might land on furniture or the ground. This separates dust particles from the air, but does not form a different type of matter. A puddle freezing into ice on a cold night is a change of state. So, it is a physical change. Liquid water freezes and becomes solid, but it is still made of water. A different type of matter is not formed. 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. A puddle freezing is caused by cooling. But dust settling out of the air is not.
