Answer 1

1. Define matter giving examples.

$\huge{\underline{\tt{\green{Answer-}}}}$

Matter - Anything that occupies space and has mass is called matter.

Example - Iron, air, table, pen, chair, fan, ice cube etc.

States of matter -

• Solid → Liquid → Gas.

Solid

• Solid have fixed shape as well as fixed volume.
• The inter particles forces of attraction are strongest in solids.
• Solids do not flow.

Liquid

• Liquid have a fixed volume but do not have fixed shape.
• Liquids can not be compressed much.
• The inter particle forces of attraction in liquid are weaker than solids.

Gas -

• Gas do not have fixed shape and fixed volume.
• Gases can be easily compressible.
• Gases flow more easily than liquid state.

2. What do you understand by the term 'intermolecular space?

$\huge{\underline{\tt{\green{Answer-}}}}$

The word intermolecular refers to the space between atom and molecule.

• There is little intermolecular space in the solid.
• Liquid have more intermolecular space than solid.
• Gas have maximum intermolecular space.
