What do these two changes have in common? melting glass grilling a hamburger

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

D

Step 1: Think about each change. Melting glass is a change of state. So, it is a physical change. The glass changes from solid to liquid. But a different type of matter is not formed. Grilling a hamburger is a chemical change. Heat from the grill causes the matter in the meat to change. Cooked meat and raw meat are different types of matter. Step 2: Look at each answer choice. Both are only physical changes. Melting glass is a physical change. But grilling a hamburger is not. Both are chemical changes. Grilling a hamburger is a chemical change. But melting glass is not. Both are caused by heating. Both changes are caused by heating. Both are caused by cooling. Neither change is caused by cooling.
