Water has a boiling point of 100°C and a melting point of 0°C. Other solvents have varying boiling and melting points.

• Water has a high boiling point due to its strong hydrogen bonding

• Solvents like ethanol have lower boiling points than water

• Melting points of solvents depend on their molecular structure

• Some solvents like mercury are liquid at room temperature

• Boiling and melting points are important in chemical reactions
