Question 2(Multiple Choice Worth 2 points)
Answers
a. The formation of gas bubbles is often the result of a chemical change (except in the case of boiling, which is a physical change). Rotting, burning, cooking, and rusting are all further types of chemical changes because they produce substances that are entirely new chemical compounds.
b. Lighting the stove and cooking the meat are both chemical changes. ... A physical change is reversible and no new substance is formed in the process. When meat is cooked, it becomes soft due to a chemical reaction that occurs.
c. Also, boiling noodles, softens the noodles due to a chemical change. When a match stick is lit, the fire that is observed occurs as a result of a chemical change (reaction).
