What's the density of the paper?

Depending on the situation, the density of paper varies from material to material. For example, 80g of high-quality copy paper has a density of 0.38 grams per cubic centimeter; fiber paper has a density of 0.2 to 1.4 grams per cubic centimeter.

Density is a measure of mass in a given volume, density is equal to the mass of the object divided by the volume, can be expressed by the symbol ρ (pronounced róu), the International System of Units and China's legal units of measurement, the density of the unit of kilograms per cubic meter.

Properties of paper

1, light: the mass of paper is relatively light compared to other objects.

2, hardness is small: paper on the invasion of external objects weak resistance, other hard objects can easily penetrate the paper sheet. Compared to metal, plastic, wood, the hardness of paper is the smallest.

3, not easy to conduct electricity: under normal circumstances, ordinary paper is not easy to conduct electricity, is basically an insulator.

4, easy to fold, plasticity: the hardness of paper is small, determines the paper can be easily folded, and folded can be maintained for a long time.

5, strong water absorption: paper is more absorbent, the cellulose in the paper is interlaced in a network, between which there are many voids, these voids can contain water.
