Question

what is matter?

Answer 1

Things that have mass and volume are matter. Mass provides a measure of the volume of matter and volume represents the amount of space taken up in space.

Matter can be classified as pure and non-pure based on its composition.

A substance that contains only one compound with a specific property, i.e. a constant composition, is called a pure substance.

A substance that contains several components is impure.

1. Solid
2. Liquid
3. Air

• Glow: - Glow due to light falling on the material
• Hardness: - The material's resistance to wear and tear
• Thermal conductivity: - The ability of heat to pass through a material
• Electrical conductivity: - The ability of electricity to pass through a material Color: - The colour possessed by the material
• Elasticity: - Flexibility when applied with force and reversing when the force is released
• Density: - Mass per unit volume
• Polarity: - The temperature at which a solid becomes a liquid during heat supply
• Boiling point: - The temperature at which a heat supply substance becomes gaseous.
