What are the three main ideas of the particulate theory of matter?
All matter is composed of tiny indivisible particles too small to see. These particles do not share the properties of the material they make up. There is nothing in the space between the particles that make up matter. The particles which make up matter are in constant motion in all physical states.
What is particulate nature of matter list three characteristics of particle nature of matter?
Particulate nature of matter means that all matter is made up of discrete tiny particles. Particles of matter have space between them. PARTICLES HAVE SPACE BETWEEN THEM. PARTICLES ARE CONTINUOUSLY MOVING.
How is the particulate nature of matter maintained?
For a given substance, the particles from which it is made maintain their properties in each state. For example, whether water is solid, liquid, or gas, it maintains the same molecular structure (H2O). The difference is in the energy of the molecules and the way they interact with each other.

What are the 5 major points of the particle theory of matter?
Terms in this set (5) All matter is made of particles. Particles have space between them. Particles are always moving. Particles move faster and get farther apart when heated.
What are the 6 particle theory of matter?
3.2 state the postulates of the particle theory of matter (all matter is made up of particles; all particles are in constant motion; all particles of one substance are identical; temperature affects the speed at which particles move; in a gas, there are spaces between the particles; in liquids and solids, the particles …
What evidence supports particulate nature of matter?
The experimental evidence of this particle or atomic nature of matter is the Brownian movement, named after the Biologist Robert Brown who was credited with its discovery in 1827.
What is the size of particles of matter?
Particle sizes are measured in microns (μ). A micron is 1/1000 mm. or 1/25,400 in. A millimicron (mμ) is 1/1000 of a micron, or 1/1,000,000 mm. Usually particle size is designated as the average diameter in microns, although some literature reports particle radius.
What are the five main points of particle theory?
Terms in this set (5)
- All matter is made of particles.
- Particles have space between them.
- Particles are always moving.
- Particles move faster and get farther apart when heated.
- Particles are attracted to each other.
What are the properties of a particle?
These include particle size, shape, surface, density, hardness, adsorption properties, etc. Of these features, particle size is the most essential and important. The term “size” of a powder or particulate material is relative.
What is the particulate nature of matter?
The Particulate Nature Of Matter 1 Matter: Matter is any substance that has mass and occupies space. 2 Changes In State Of Matter: 3 Heating Curve: The above figure shows a heating curve of a solid. 4 Cooling Curve: The above figure shows a cooling curve of a gas.
What is the nature of matter?
Matter is anything that occupies space and has mass. Matter commonly exists in three states i.e. solid, liquid and Gas The process of sub-dividing matter into smaller units and smaller units continues indefinitely, suggesting that matter is not continuous, but is made up of even smaller parts e.g.
What happens to the particles when a solid becomes a liquid?
Eventually, the particles will have enough separation to move past one another, but still kept relatively close (as attractive forces between particles still exist). The solid has now officially become a liquid.
Why do solids have particles packed together?
Solids have particles that are packed closely together. The atoms are arranged in a regular pattern due to the strong attractive forces that exists between the particles. These particles therefore cannot move. Instead, they vibrate constantly on the spot.
