Question

A sheet of wood floats on water. This implies

• A. density of water is less than the density of wood.
• B. density of wood is less than the density of water.
• C. weight of wood is less than the weight of water.
• D. weight of water is less than the weight of wood.

Answer 1

The correct option is B

density of wood is less than the density of water.

1. Anything floats in water when it weighs less than the amount of water it would have to push out of the glass if it sank.
2. Wood, cork, and ice are all less dense than water, and they float while the rocks are denser, so they sink.
3. If we compare the weight of wood and an equal amount, or volume, of water, the sample of wood would weigh less than the sample of water.
4. It means that wood is less dense than water.
5. Since wood is less dense than water, wood floats in water, no matter how big or small the piece of wood is.

Hence, the correct answer is option B. A sheet of wood floats on water. This implies that the density of wood is less than the density of water.
