Question

Water is liquid at room temperature. Which of the following is the correct reason to justify it?

• A. In water, the inter molecular forces are strong enough to keep its particle bound with each other
• B. The melting point of water is below room temperature
• C. Its boiling point is above room temperature
• D. All of above

Answer 1

Answer: (D)

All of above

The intermolecular force of attraction between the water molecules is strong enough to keep the molecules/particles bound to each other. The melting point of water is below room temperature as it is already present in the liquid state whereas, its boiling point is above room temperature, i.e; ${100}^{o}C$ and room temperature is ${20}^{o}C-{22}^{o}C$
