1)mass per unit volume

2)The density of that block on cement is very high, unlike that bunch of cotton.

MASS:

1)the quantity of matter- related to weight, but cannot change

2)That fat man has so much mass!

VOLUME:

1)the amount of space, measured in cubic units, that an object or substance occupies/contains

2)That container has lots of volume, or space.

WEIGHT:

1)the amount or quantity of heaviness; how heavy an object is

2)The weight of that pen is about a few ounces.

Sorry, I don’t know about Characteristic Property. I have not learnt it yet, because I am in 6th grade…:)

Hope this helped!!

In physics, density is mass m per unit volume V.

Mass is a fundamental concept in physics, roughly corresponding to the intuitive idea of “how much matter there is in an object”.

In informal everyday usage, mass is more commonly referred to as weight,

A substance has characteristic properties, such as density, a boiling point, and solubility, all of which are independent of the amount of the sample. A mixture of substances often can be separated into the original substances using one or more of the characteristic properties.

The volume of a solid object is the three-dimensional concept of how much space it occupies, often quantified numerically. One-dimensional objects (such as lines) and two-dimensional objects (such as squares) are assigned zero volume in the three-dimensional space.

In the physical sciences, weight is a measurement of the gravitational force acting on an object. In everyday parlance (and, for historical reasons, still in some scientific terminology), “weight” is often used as a synonym for mass

Summary

Mass: How much of something there is

Weight: The mass multiplied by the Earths Gravitational Field
