FAQs
Why is water often referred to as the “universal solvent”?
Water’s unique polarity allows it to dissolve a wide range of substances, earning it the title of the “universal solvent.”
What is the significance of water’s high heat capacity?
Water’s high heat capacity enables it to absorb and store large amounts of heat, helping to regulate Earth’s temperature.
How does water’s density change with temperature?
Water’s density is highest at 4°C, which is why ice floats on water and aquatic life can thrive beneath ice sheets.
Can water exist in a supercooled state?
Yes, water can remain a liquid below its freezing point if it lacks impurities and is not disturbed.
Why is water often used as a benchmark in scientific experiments?
Water’s consistent and well-understood properties make it an ideal reference point in scientific research.
What are the potential consequences of water scarcity?
Water scarcity can lead to drought, crop failures, and even conflicts over access to freshwater resources.
