Question 126 • PA-Physical Science A

A log has a density of .8 g/cm³. What will happen to this log in freshwater, which has a density of 1.0 g/cm³?

Answer
A
It will sink.
B
It will float.
C
It will move deeper.
D
It will decrease in density.

Explanation

An object floats when its density is lower than the density of the fluid around it. The log’s density is 0.8 g/cm³, which is less than freshwater’s density of 1.0 g/cm³, so the log will float.
