Question

Give reason for the following:

The boiling point of tap water is above 100 °C.

Answer 1

• The boiling point is the temperature at which a liquid turns into its gaseous state.
• The boiling point of pure water is 100 °C.
• Tap water has many impurities present in it along with water.
• Microbial and organic contaminants are the most common impurities found in water.
• Aluminum, ammonia, copper, mercury, silver, and many other impurities are also there.
• The two most common toxic chemicals found in tap water are chlorine and fluoride.
• Impurities present in any liquid raises its boiling point.

Hence, the tap water boils at a temperature of more than 100 °C due to the presence of impurities in it.
