Question

Explain why water and solutions with water as the solvent boiled at temperatures lower than 100°c

Answer 1

Below

Step-by-step explanation:

Water boils at 100°C at sea level under standard atmospheric pressure.

However, the boiling point of a solution, such as a sugar solution, can be lower than the boiling point of pure water.

This is because the presence of solute molecules in the solution reduces the energy needed for the water molecules to escape from the surface of the solution and enter the air as steam.

As a result, the solution will begin to boil at a lower temperature than pure water.
