Nothing at all. The density of one penny is the same as the density of a truckload of pennies, or of a cargo-ship-load of the metal that's used to make pennies out of.
Differences in density in the air or gases (due to the heat) produce refraction. These differences in density change from one moment to another.
The closer the tufts are together the higher the "density" the higher the density the more fiber there is in each sq inch to support the load & take the abuse. There is a formula for calculating density 36XFace weight divided by the pile height= Density If kind & yarn and all other things are equal the carpet with the highest density # the better it should perform over time.
Buoyancy force come from difference in density of the object and the surrounding. Buoyancy of the ship can change from the pay load inside its' space. More load per space reduce the buoyancy. For Balloon, buoyancy is change by increase temperature of gas inside to balloon since increase in temperature would cause gas to expand and had lesser density in its' cavity. In general, buoyancy increase or decrease by changing of density of the object or the surrounding medium.
Many combustible substances (substances that will burn) are lighter (less dense) than water and will float - paper, wood and gasoline are a few examples. When ignited (set on fire), these substances will continue to float, and so will the fire.
Rock.
The denser the styrofoam, the greater it's load bearing ability.
It is the maximum weight that can be safely loaded on a unit area..
You can down load Catching Fire on Amazon.com to your Kindle.
Because of the risk of fire
Hurricanes
Load th cannon UP and fire it!
Load, aim, release safety, pull trigger.

Fire is a combination of heat and light energy emitted by a chemical reaction, and as such it has no mass and therefore no density.
It gives density to the sample that we load and also it avoids diffusion of sample
