Question 14 • GA-GSE Physical Science A

Wax melts when it is heated. Which most likely describes what is true of the result of this reaction?

Answer
A
The bonding of the atoms is not the same before and after the change.
B
The wax has the same density before and after the change.
C
The same amount of wax exists before and after the change.
D
The wax cannot be changed back into a solid.

Explanation

Melting changes wax from a solid to a liquid, but it does not create or destroy the wax. The same amount of wax exists before and after the change, so choice C is correct. The wax can also become solid again when it cools.
