Question

tearing a magazine page is an example of

a combustion.
b compression.
c a physical change.
d a chemical change.

Explanation:

Analyze the action of tearing paper

Tearing a magazine page changes its shape and size, but the chemical composition of the paper remains completely identical.

Compare with the options

• Combustion is a chemical reaction (burning).
• Compression is a reduction in volume under pressure.
• A physical change alters the form of a substance without changing its chemical identity.
• A chemical change results in the formation of new chemical substances.

Determine the correct classification

Since tearing only changes physical appearance and does not create new substances, it is a physical change.

Answer:

• (A) combustion.
• (B) compression.
• (C) a physical change. (Correct answer)
• (D) a chemical change.
