## What are the densities of common substance?

Densities of Common Substances

Material Density (g/cm3) State of Matter
ice 0.920 solid
water at 20°C 0.998 liquid
water at 4°C 1.000 liquid
seawater 1.03 liquid

What density contains?

mass per volume
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 the most common density?

The SI unit of kilogram per cubic metre (kg/m3) and the cgs unit of gram per cubic centimetre (g/cm3) are probably the most commonly used units for density. One g/cm3 is equal to 1000 kg/m3.

### What two factors affect density?

The size, mass, and arrangement of atoms affect the density of a substance.

What are the factors that do not affect the density?

In other words, the size or amount of a material/substance does not affect its density.

#### Which is the least densest?

The world’s least dense solid is a graphene aerogel with a density of just 0.16 mg/cm³; produced by a research team from the Department of Polymer Science and Engineering lab at Zhejiang University, China, headed up by Professor Gao Chao (China). The material was announced in Nature magazine on 27 February 2013.

#### What is the most dense liquid?

This is because corn syrup has the highest density of all the liquids, about 1.4 grams per cubic centimeter whereas the density of water is about one gram per cubic centimeter at room temperature.

What are the densities of the most common substances?

Densities of Common Substances Material Density (g/cm 3) State of Matter ice 0.920 solid water at 20°C 0.998 liquid water at 4°C 1.000 liquid seawater 1.03 liquid

## How is the density of a substance measured?

Here’s a table of densities of common substances, including several gases, liquids, and solids. Density is a measure of the amount of mass contained in a unit of volume.

## Which is less dense a liquid or a gas?

Updated May 06, 2019. Here’s a table of densities of common substances, including several gases, liquids, and solids. Density is a measure of the amount of mass contained in a unit of volume. The general trend is that most gases are less dense than liquids, which are in turn less dense than solids, but there are numerous exceptions.

What are the densities of hydrogen and nitrogen?

Material Density (g/cm 3) State of Matter hydrogen ( at STP) 0.00009 gas helium (at STP) 0.000178 gas carbon monoxide (at STP) 0.00125 gas nitrogen (at STP) 0.001251 gas
