The measure of the quantity of matter in an object is called mass. Mass is commonly measured in units such as kilograms or grams.
The smallest units of matter are the subatomic particles.
The amount of matter making up an object is called its mass. Mass is a measure of the quantity of matter contained within an object, and it is typically measured in units such as kilograms or grams.
The measure of the amount of matter an object contains is called its mass. Mass is typically measured in units such as grams or kilograms.
The amount of matter in an object is called its mass. Mass is a measure of the total quantity of particles in an object and is typically measured in units like grams or kilograms.
The amount of matter an object is made of is called its mass. This mass is a measure of the quantity of matter in the object and is typically measured in units such as grams or kilograms.
No two units of matter can occupy the same space at once. This is one of the primary properties of matter.
The atoms
Gottfried Leibniz
When molecules are broken down into smaller units, they are called atoms. Atoms are the basic building blocks of all matter and cannot be further divided into smaller particles without losing their chemical properties.
The space occupied by matter is called volume. It is a measure of the amount of three-dimensional space that an object or substance occupies. Volume can be measured in cubic units such as cubic centimeters or cubic meters.
