Question

a student conducted an investigation about density. the materials used were water, liquid 2, object x, and object y. the results of the investigation are shown. which option shows the correct order of the materials from lowest to highest density? a object x, object y, water, liquid 2 b water, liquid 2, object x, object y c water, object x, liquid 2, object y d object x, water, object y, liquid 2

Explanation:

Step1: Recall density - floating relationship

Less - dense objects float on more - dense liquids.

Step2: Analyze in water

Object X floats on water and Object Y sinks in water, so density of Object X < density of water < density of Object Y.

Step3: Analyze in Liquid 2

Both Object X and Object Y float on Liquid 2, so density of Object X < density of Object Y < density of Liquid 2. Also, since Object X and Y float on Liquid 2 but Object Y sinks in water, density of water < density of Liquid 2.

Answer:

D. Object X, Water, Object Y, Liquid 2
