Concept Introduction:
State of matter:
Matter exists in four states.
i.e. Solid, liquid ,gas, plasma
Solid- In a solid, particle are closely packed together and unable to move about very much.
Particle of a solid have very low kinetic energy.
The electrons of each atom are in motion, and vibrate little. They have fixed proportion, and definite shape. They have also definite volume.
The particle connected with each atom so tightly so it could not reduce to smaller volume itself.
Liquid-In a liquid, particle are less loosely bound than solid and have more kinetic energy than solid.
The liquid particle is not held in regular shape.
They have acquired volume, means it contain the volume of the container in which it stored.
A liquid will change shape to conform to its container.
Force is separated evenly throughout the liquid.
Gas-Gas particle have a great deal of space between them and have high kinetic energy.
The particle of gas can be spread out indefinitely and if confined, the gas will spread throughout the container.
Gas can be pressurised to reduce its volume and space between the gas paricle will reduced& pressure increases during the collision process.
When the volume of the container held constant, if the temperature increased means the pressure also increased
Gas particle have enough kinetic energy to overcome intermolecular forces that hold by solid or liquid or together.so the gas has no definite volume and shape.
Mixture:
It is a mixture which made up of two or, more different substance with definite proportion or has any amount of ingredient.
Mixture is classified into two types:
1) Homogeneous mixture.
2) Heterogeneous mixture
(b)
Interpretation: The following diagram shown in question as a solid, liquid, gas or mixture of two substance should be identified.
