Question

Gina is sitting by a stream. She sees a clam shell on the bottom of the stream. An acorn falls in the stream and floats on the water. A wooden stick also floats by. Which object that Gina saw has the greatest density? A. Wooden stick, B. Clamshell, C. Acorn, D. Water

Answer 1

B. Clamshell

Step-by-step explanation:

Density is defined as mass per volume. The density of an object decides whether that object will sink or float if placed in water.

An object with higher density sinks in the water while an object with less density floats in water. In the given example, Clamshell has the highest density as it sinks in the water while other objects' wooden stick and acorn float over the water.

Clamshell has the highest density than water as well because the object has more weight per unit of volume and the buoyancy force of water decreases that allow the object to sink.

Hence, the correct answer is "B. Clamshell".
