Chapter 4: Problem 21

What substances would sink in gasoline but float in water?

Short Answer

Expert verified
Answer: Examples of substances with intermediate densities between gasoline and water are ice (with a density of 920 kg/m3) and some types of plastic (with densities ranging from 800 to 950 kg/m3). These substances sink in gasoline but float in water.

Step by step solution

01

Compare Densities

First, compare the densities of water and gasoline. The density of water is 1000 kg/m3, and the density of gasoline is around 700 kg/m3.
02

Find Substances With Intermediate Densities

Next, find substances with densities between that of gasoline and water, i.e., substances with densities between 700 kg/m3 and 1000 kg/m3.
03

Example of Intermediate Density Substances

Some examples of substances with intermediate densities between gasoline and water are: 1. Ice (with a density of 920 kg/m3) 2. Some types of plastic (with densities ranging from 800 to 950 kg/m3) These substances would sink in gasoline but float in water, as their densities lie between the densities of gasoline and water.
