Answer to Problem 55A
Aluminum is the densest substance.
Explanation of Solution
With increase in volume, density of the substance decreases. The increasing order of volume in solid liquid, and gas are as follows:
Gas>Liquid>Solid
And increasing density order is as follows:
Solid>Liquid>Gas
The density of air, water, ethanol, or aluminum is
Density of a substance is high if its volume is less than its mass.
