Do you know about the behavior of matter? If not, then to know the behavior of the matter or read the article carefully?
Matter: It’s states and behaviours
When we talk about matter, then one thing comes to our mind that what is matter, in which all the things are there.
Made up of all matter, even we humans are made of matter only.
Everything around us is made up of matter.
This means that if we talk about matter, then all the things in the world, all the things around us, all get involved in matter.
What is matter in science:
If we talk in the language of science, then we can say that whatever things fall into space, and which have mass, they will be included in the matter.
Simply we can say that- “Anything that occupies speed and has mass are matters”
These particles are so small that we cannot see them with the naked eye, they need a microscope to see them, they are several nanometres small, which are impossible to see with the eye, there is a distance between these particles, between which These particles keep on moving continuously, due to the distance between these particles, their shape and size are divided, on the based one shape and size, the matter is divided into three parts.
We will go into detail about all three…
Matter in the solid
solid-state space between the two is called the intermolecular space.
This is the same place where the movement of particles takes place.
In the solid state, the distance of the molecular space between the molecules is very small, so they cannot move very far.
Molecules of matter exert a kind of force on each other so that they cannot move at a much distance from each other, this applied force is called intermolecular force.
That is why the size and mass of the solid are immutable or fixed due to the negligible motion of the molecules in the solid state.
Understand in one lines…..
In the solid state molecules have Strong intermolecular force.
In the solid state the distance between two molecules is very small
That’s why the mass of the substance in the solid state, density, melting point, boiling point, are all high.
That is why the shape and size is fixed in the solid state.
That’s why solid con not be compressed and flow.
Matter in the Liquid state
Liquid like water, petrol etc.
The distance between the molecules of the liquid is greater than that of the molecules of the solid state.
For this reason, the intermolecular force applied between them is also less than that of the molecules of a solid substance, there is a constant movement between the molecules of these as well.
Due to the large intermolecular space, it can move freely for a greater distance.
For this reason, the shape of the matter is not fixed in the liquid state and the liquid assumes the shape of the vessel in which we keep it.
Also, this is the reason that liquids tend to flood the density of the liquid is lower.
More to know in one line......
Liquid has a large molecular space than solid-state.
Liquid has a strong molecular force between its molecules than solid-state.
That’s why The liquid has no definite shape and size.
So that density of the liquid is lower, and low melting and boiling points also.
The liquid can be compressed and can flow.
Matter in the Gaseous state
Gas is present all around us.
Gas molecules are located at a great distance from each other, and the intermolecular force and intermolecular force acting between them are negligible.
There is such a distance between their molecules that the force of attraction of one molecule on the other is negligible, so its molecules can move freely, that is why the gas does not remain stationary.
It has neither shape nor density.
More to know in one line…..
1. Gases have negligible molecular force.
2. Gases have negligibleble molecular space between the molecules.
3. Gases have no definite shape and size.
4. It has no density.
5. Gases can be highly compressed.
6. Gases can flow.
Q1- what are the differences in nature and behaviour?
Answer -Behavior is the way in which one acts or conducts oneself, especially toward others. Behavior is usually adaptable or not consistent. Nature is the basic or inherent features of something, especially when seen as characteristic of it. Nature is usually not adaptable or inconsistent.
Q2 What is the physical nature of matter?
Answer-Matter is made up of particles. Everything around us is made up of tiny pieces or particles. The particles of matter are constantly moving (they are in motion). The particles which make up matter are atoms and molecules.
Q3-what is the nature of matter in chemistry?
Answer -The following is the nature of matter : Atoms that have protons, neutrons, electrons and a nucleus consist of matter. It generally exists in four states i.e. liquid, solid, gaseous and plasma state. The universe itself is a matter. Not all forms of energy are matter.
Q4-what is the nature of particles in matter?
Answer- The particle model of matter states that all matter is made up of tiny, moving particles with spaces between them.
Q5-what are some natural behaviour of matter?
Answer -We defined natural behavior as behavior that animals have a tendency to perform under natural conditions because these behav- iors are pleasurable and because they promote biological functioning. It includes behaviors such as foraging, grooming, exploration, and play.
Q5- how many nature of matter do you have?
Answer -There are four natural states of matter: Solids, liquids, gases and plasma. The fifth state is the man-made Bose-Einstein condensates.
Q7-how is matter continuous in nature?
Answer-Matter is composed of very small particles called atoms, hence matter is not continuous but particulate in nature. However, there is another nature associated with matter, which is wave like nature.
