Matter Properties
What is Matter?
Matter properties: Anything that has a density that surrounds the space and which we can feel by one or more senses is called Matter. Like – air and water; Hydrogen and oxygen; Sugar and sand; Silver and steel; Milk and oil; Carbon dioxide and steam; Carbon and sulfur; etc. These are a variety of hot substances that have mass, volume, and space that surround them. They are present in the form of solid, liquid, gas, and plasma.
OR
The substances that surround the space, which have a fixed mass, which can exert pressure; Can produce physical resistance, and whose existence can be felt by our senses, called Matter.
States of Matter
There are three states of matter, These states are:
- Solid
- Liquid
- Gas
Solid: Materials that have a fixed size, and a constant volume, are called solids.
The concrete retains its shape even when exerted by external force. The concrete breaks down by applying more force but does not change its shape.
Examples: iron, coal, utensils, chairs, tables, etc.
Liquid: The substances whose size is uncertain and volume is called fluid or liquid.
A fluid or fluid takes the shape of the vessel in which it is placed. Examples: water, oil, milk, etc.
Gas: The gas circulates freely in each direction and fills the entire available space regardless of volume. It consists of particles that do not have a certain amount and size. Examples: air, oxygen, nitrogen, smoke, etc.
In gas, molecules are loosely held, so there is plenty of space between molecules to move freely. Due to this feature, gas can fill any container.
Characteristic properties of particles of matter
1.Gap between particles of matter: When we make tea, lemon-water, etc., particles of one substance become incorporated into the spaces of particles of another substance. That is, the space between particles of matter is sufficiently empty.
2. Constant movement of particles of matter: Particles of matter are continuously moving, and have kinetic energy, due to which the speed of particles also increases as the temperature increases. Therefore, the kinetic energy of the particles also increases as the temperature increases.
3. Particles of matter attract each other: A force acts between the particles of matter and this force holds the particles together. The strength of this attraction force is different in every substance, so it can be said that particles of matter attract each other.
