Having both volume and mass
Explanation
Matter is defined as anything that has both volume and mass. Being made of particles describes the corpuscular model, not the definition of matter itself.
Matter is made of particles
Explanation
The corpuscular model is a scientific model based on the idea that matter is made of particles. Matter itself is the substance being described, rather than the model used to explain it.
The smallest particle of matter that cannot be divided chemically
Explanation
An atom is the smallest particle of matter that cannot be divided chemically. A group of chemically bonded atoms is a molecule, not an atom.
Two or more atoms chemically bonded together
Explanation
A molecule consists of two or more atoms joined by chemical bonds. A single chemically indivisible particle corresponds to an atom, while mass and volume define matter.
The particles move more rapidly
Explanation
The corpuscular model states that increasing temperature increases the motion of particles. Attractive forces help hold particles together, but they do not describe the direct effect of raising temperature.
Democritus, a Greek philosopher
Explanation
Democritus was a Greek philosopher regarded as the first thinker to suggest that matter is made of particles. The corpuscular model is the later scientific model built around this general idea.
