Identify the state:
It can have any number of free surfaces.
Identify the state:
It can have any number of free surfaces.
Matter
- Anything that occupy space and has mass is known as matter.
- It can be perceived by our sense organs.(Nose, ear, eye, tongue and skin)
- Matter can be physically classified into three states: Solid, Liquid and Gas
- Difference between solid, liquid and gas on the basis of number of free surface:
SOLID
LIQUID
GAS
1. Particles have strong intermolecular force of attraction. 1. Particles have less intermolecular force of attraction as compared to solids. 1. Particles have very less intermolecular force of attraction as compared to solids and liquids. 2.It is a state of matter which has definite volume and definite shape. 2. It is a state of matter which has definite volume but indefinite shape. 2. It is a state of matter which has indefinite volume and indefinite shape. 3. The surface which is in contact with the air is known as the free surface of the solid. There is an infinite free surface in solids.
3. The surface which is in contact with the air is known as free surface of the liquid.
There is only one free surface in liquid.
3. The surface which is in contact with the air is known as free surface of the gas. There is no free surface in gases as they have a tendency to occupy the entire space of the container. 5. Example:
Cane sugar crystal in a container contains an infinite free surface.
5. Example:
Water in glass contains one free surface which is horizontal and in direct contact with air.
5. Example: Nitrogen gas in container has no free surface.
It can have any number of free surfaces is solid state.
