Question

question 26.
which material should never be placed in the microwave?
a. ceramic
b. metal
c. paper
d. plastic

Explanation:

Microwaves interact with materials by causing water molecules to vibrate. Metal reflects microwaves, which can cause arcing, fires, or damage to the microwave. Ceramic, paper (non - metallic, non - flammable types), and some plastics (microwave - safe) can be used. So metal should never be placed in a microwave.

Answer:

B. metal
