Q1. What is boiling and melting point in exact word?
Ans. 
Boiling point is the temperature at which a liquid turns into a gas, while melting point is the temperature at which a solid turns into a liquid.
• Boiling point is dependent on atmospheric pressure.

• Melting point is dependent on the substance's intermolecular forces.

• Water boils at 100°C and melts at 0°C at standard pressure.

• Different substances have different boiling and melting points.

• Boiling and melting points can be us
