Question

a student drops five objects into a container of water. which statement best classifies some of these objects? a objects 2 and 5 are more dense than water, while objects 1 and 4 are less dense than water. b objects 1 and 4 are more dense than water, while objects 2 and 3 have the same density as water. c objects 2 and 3 are less dense than water, while object 5 is more dense than water. d objects 1 and 4 are less dense than water, while object 2 is more dense than water.

Explanation:

Step1: Recall density - buoyancy relationship

Objects less dense than water float, and objects more dense than water sink.

Step2: Analyze object positions

Objects 1 and 4 are floating on the water surface, so they are less dense than water. Object 2 is at the bottom of the container, so it is more dense than water. Object 5 is suspended in the water, which means its density is equal to that of water, and objects 3 is at the bottom, more dense than water.

Answer:

D. Objects 1 and 4 are less dense than water, while Object 2 is more dense than water.
