Concept explainers
Interpretation:
Name of the scientist who proposed the concept that matter is composed of tiny, indivisible particles is to be discussed.
Concept introduction:
Any substance that has mass and occupies space by having a fixed volume is matter. Everything that exists is a matter, for example, table, chair, coins, etc.
Answer to Problem 30A
The scientist who proposed the concept that matter is composed of tiny, indivisible particles was Democritus.
Explanation of Solution
Greek philosopher Democritus proposed the concept that matter is composed of tiny, indivisible particles. The hypothesis stated that:
- Atoms move through empty space.
- They are solid, indestructible, homogenous and indivisible in nature.
- Different atoms have different sizes and shapes.
- The properties of matter are determined on the size, shape and movement of the atom.
Democritus was the first scientist to propose the concept that matter is composed of tiny indivisible particle.
