Answer:
Solid, liquids and gas are the three states of matter.
Materials which we see in our daily lives such as ice-cream, chair, water etc. are made up of the matter. Matter can be classified as solid, liquid and gas on the basis of inter-molecular forces and the arrangement of particles. These three forms of matter can be converted from one state of matter to another state by increasing or decreasing pressure and temperature.
Change in state of matter alters the structure of matter and the arrangement of particles. All of this can be observed by noticing the change in properties.
Three States of Matter
Three States of Matter – Solid, Liquid and Gas
Three States of Matter with Examples
There are three states of matter and below are the description of various states of matter:
1. Solids
The Solid state is one of the fundamental states of matter.
Solids differ from liquids and gases by the characteristic of rigidity.
The molecules of solids are tightly packed because of strong intermolecular forces; they only oscillate about their mean positions.
Whereas, liquids and gases possess the property of fluidity and can easily flow.
Solids can be defined as the state of matter which has definite shape and volume and has a rigid structure.
Solids possess the least compressibility and thermal expansion.
Example: Iron (Fe)
Solid State of Matter
2. Liquids
The molecules in a liquid are closely packed due to weak intermolecular forces.
These forces are weaker than solids but stronger than that of gases.
There is much space in between the molecules of liquids which makes their flowing ability easy.
Liquids can easily acquire the shape of a vessel and they have a fixed volume.
Conversion of solids into liquids takes place when we increase the temperature of solids to a point where solids begin to melt.
Generally, the density of liquid lies between the density of solids and gases. Compressibility and thermal expansion of liquids are slightly higher than that of solids.
Example: Water (H2O)
Liquid State of Matter
3. Gases
In this state of matter, distances between the molecules are large (intermolecular distance is in the range of \(10^{-7} – 10^{-5} cm\))).
The intermolecular forces experienced between them are negligible.
Thus translatory, rotatory and vibratory motions are observed prominently in gases.
Gases do not have any fixed shape or volume.
They also possess high compressibility and thermal expansion.
Example: Oxygen (O2)
4. How is matter made up?
Ans: Matter is also composed of small particles. Atoms are the particles that makeup matter. Because they are so small you can’t see atoms. Most atoms come together to make up the substance you can see.
5. Is light a matter?
Ans: Light is, not matter, a form of energy. Matter consists of atoms. Actually, light is electromagnetic radiation. Moving electrical charge or electrons (electrical current) causes a

1. Can Matter exist in two states at once?
Ans: Pressure can turn matter from one state to another. Certain matter often varies, but often only occurs in two states and requires human and technical help to travel through all three stages. Water is the only thing on earth that can naturally be present in all three-solid, liquid and oil.
2. How do you explain the matter?
Ans: Matter is all about you. All atoms and compounds are made up of very small pieces of matter. Such atoms continue to build the everyday things you see and touch. Matter is defined as anything that has mass (it has volume) and takes up space.
3. Why are the 3 states of matter important?
Ans: Three types of matter are solids, liquids, and gases. Comprehending the particle nature of matter is significant. Particles that makeup matter are not ‘ small solid bits ‘ or ‘ small liquid drops, ‘ but atoms and molecules. Such atoms and molecules ‘ physical characteristics determine their state.

5. Is light a matter?
Ans: Light is, not matter, a form of energy. Matter consists of atoms. Actually, light is electromagnetic radiation. Moving electrical charge or electrons (electrical current) causes a magnetic field and a changing magnetic field creates an electrical or electrical field.
