Question

State of matter explain


​

Answer 1

Answer:

In physics, a state of matter is one of the distinct forms in which matter can exist. Four states of matter are observable in everyday life: solid, liquid, gas, and plasma. ... Matter in the liquid state maintains a fixed volume, but has a variable shape that adapts to fit its container.

Answer 2

Answer:

States of Matter

There are three states of matter – solid, liquid and gas.

SOLIDS:

Matters which have fixed volume and shape are called solids. For example - stone, wood, brick, ice, sugar, salt, coal, etc. All metals are solid except mercury and gallium.

Properties of solids

• Solid has fixed volume.
• Solid has fixed shape.
• Solid has high density.
• Solids are heavy.
• Solid does not flow.

LIQUIDS:

Matters which have fixed volume but indefinite shape are called liquids. For example - milk, water, petrol, kerosene, alcohol, oil, etc. Since liquid can flow, it is also called fluid.

Properties of liquid

• Liquid has definite volume.
• Liquid has no definite shape.
• Liquid gets the shape of container in which it is kept.
• Liquid cannot be compressed much.
• Liquids has less density compare to solid.
• Liquid is lighter than solid.
• Liquid flows and hence is called fluid.

GAS:

Matters which have indefinite shape and volume are called gases. For example - air, oxygen, hydrogen, nitrogen, carbon-dioxide, etc.

Properties of gas

• Gas has indefinite shape
• Gas has no fixed volume.
• Gas gets the shape and volume of container.
• Gas fills the container completely.
• Gas has very low density.
• Because of low density gas are light.
• Gas can flow easily and hence are called fluid.
