Question

The density of ocean water increases when it

a. joins the Gulf Stream.
c. gets warmer.
b. gets colder.
d. turns to ice. Please select the best answer from the choices provided A B C D

Answer 1

Answer: Option (b) is the correct answer.

Step-by-step explanation:

Density means the degree of compactness, that is, when particles of an object or substance are closer to each other then it is said that density of object is high.

Therefore, when ocean water gets colder then particles of water will gain potential energy and thus they will come closer to each other. Hence, there will be increase in density of ocean water when it gets colder.

Answer 2

The correct answer is (b.) gets colder. The density of the ocean water increases when the water gets colder. Therefore, it is already concluded that the density of the water and its temperature is indirectly proportional since as the density increases, the temperature decreases.
