Convection

Question 1 • Fall 24 GSE Physical Science B IC

Which statements accurately describe convection in water? Check all that apply.Cold water sinks because it is less dense than warm water.Cold water sinks because it is more dense than warm water.Cold water rises because it is more dense than warm water.Warm water sinks because it is less dense than cold water.Warm water rises because it is less dense than cold water.Warm water rises because it is more dense than cold water.

Answer
A
Cold water sinks because it is less dense than warm water.
B
Cold water sinks because it is more dense than warm water.
C
Cold water rises because it is more dense than warm water.
D
Warm water sinks because it is less dense than cold water.
E
Warm water rises because it is less dense than cold water.
F
Warm water rises because it is more dense than cold water.

Explanation

In typical convection, colder water is denser than warmer water, so it sinks. Warmer water is less dense than colder water, so it rises. Therefore, the accurate statements are “Cold water sinks because it is more dense than warm water” and “Warm water rises because it is less dense than cold water.”
