What do these two changes have in common? water freezing into ice dry ice sublimating and becoming a gas
[ "Both are only physical changes.", "Both are caused by cooling.", "Both are caused by heating.", "Both are chemical changes." ]
A
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. Dry ice is solid carbon dioxide. When dry ice gets warm, it changes state and becomes carbon dioxide gas. This change of state, from solid to gas, is called sublimation. Dry ice becoming a gas is a physical change. A change of state does not form a different type of matter. 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. Dry ice sublimating is caused by heating. But water freezing into ice is not. Both are caused by cooling. Water freezing is caused by cooling. But dry ice sublimating is not.

What do these two changes have in common? silver jewelry tarnishing baking a loaf of bread
[ "Both are only physical changes.", "Both are chemical changes.", "Both are caused by heating.", "Both are caused by cooling." ]
B
Step 1: Think about each change. Metal turning less shiny over time is called tarnishing. Silver jewelry tarnishing is a chemical change. The silver reacts with sulfur in the air to form black tarnish. The tarnish is a different type of matter that was not there before the change. Baking a loaf of bread is a chemical change. The type of matter in the dough changes when it is baked. The dough turns into bread! Step 2: Look at each answer choice. Both are only physical changes. Both changes are chemical changes. They are not physical changes. Both are chemical changes. Both changes are chemical changes. The type of matter before and after each change is different. Both are caused by heating. Baking is caused by heating. But silver tarnishing is not. Both are caused by cooling. Neither change is caused by cooling.
