Compressed air is MORE dense than expanded air. Density is the measure of an objects mass (measured in grams, kilograms, pounds etc) divided by its volume (cubic centimetres, litres, cubic feet, cubic yards etc).
D= m/V
Decreasing the volume of an object, or in this case a fixed amount of air, increases the density because the mass does not change but the volume gets smaller. Increasing the volume (expanded air) causes the density to decrease.

Is a cannon ball more or less dense than a water balloon the same size?

How dense must an object be to float in the water?
Less dense than the water.
Why does puffed puri float and flat sink?
Puffing it up makes it less dense. Anything less dense than water can float on water, and anything more dense than water will sink.
Is water denser than oil?
No, in general most oils are LESS dense than water.
Does compressed air last longer in paintball?
No, Compressed air lasts much less than a comparably sized C02 tank. This is because CO2 is stored in liquid form, which is much more dense and takes up less space.
Is ice less dense or more dense than water?
no
How do reduce density of concrete?
Add ballast that is less dense than the gravel/sand in the concrete such as LECA (Light Expanded Clay Aggregate).
Is ammonia more dense or less dense than air?
Yes ammonia is less dense than air
What is always less dense than solids?
Gases are less dense than solids.
Is saliva less dense than oil?
No, oil is less dense than saliva.
What object is less dense than water?
A wooden block can be less dense than water.
Is water less or more dense than water?
Ice is less dense than water
Is chalk less dense than salty water?
No, it is more dense. If it were less dense it would float.
Can you make oil less dense than water?
Oil IS already less dense than water.
Is less dense than?
Your question is hard to answer for you have not made it clear what you are asking. The term "is less dense than?" is not a question. If you were to ask "What is less dense than snow or water?" That would be a correct question.
Which cold solid is less dense than the liquid when it melts?
Ice is a solid less dense than the liquid
