## What is an example of an object that is very dense?

Examples of dense materials include iron, lead, or platinum. Many kinds of metal and rock are highly dense. Dense materials are more likely to ‘feel’ heavy or hard.

What has a lot of density?

Solids

Substance Density(g/cm^3)
Platinum 21.45
Plutonium 19.84
Rubber 1.506
Silver 10.49

What are the densest things?

At the modest temperatures and pressures of Earth’s surface, the densest known material is the metallic element osmium, which packs 22 grams into 1 cubic centimetre, or more than 100 grams into a teaspoonful. Even osmium is full of fluff, however, in the form of electron clouds that separate the dense atomic nuclei.

### What common substance has the highest density?

Osmium
The first chemical element with the lowest density is Hydrogen and the highest density is Osmium.

What objects have a density of 1?

Densities of Common Substances

Material Density (g/cm3) State of Matter
water at 4°C 1.000 liquid
seawater 1.03 liquid
milk 1.03 liquid
coal 1.1-1.4 solid

What is density simple?

Density is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water).

#### What is an example of a dense object?

Examples of dense materials include iron, lead, or platinum. Many kinds of metal and rock are highly dense. Dense materials are more likely to ‘feel’ heavy or hard. Although a sparse material (sparse is the opposite of dense) can feel heavy if it’s really big.

Why do dense objects sink?

Objects with tightly packed molecules are more dense than those where the molecules are spread out. Density plays a part in why some things float and some sink. Objects that are more dense than water sink and those less dense float. Hollow things often float too as air is less dense than water. This is partly why huge heavy ships float.

What are dense objects?

Density is a way to measure how tightly packed an object is. Denser objects have less empty space in them, they are less holey. The density of an object is often measured in grams per milliliter.

## What is a low density material?

LDPE (low density polyethylene) is a soft, flexible, lightweight plastic material. LDPE is noted for its low temperature flexibility, toughness, and corrosion resistance.
