Water is probably the most common liquid that we drink throughout our lives. Water is all around us, from the rain to the water on the shelves of stores, we sometimes forget how important water is in our daily lives. Here are some little-known facts that you may or may not know about water.
- A person can live about a month without food, but only about a week without water.
- Water expands by 9% when it freezes. Frozen water (ice) is lighter than water, which is why ice floats in water.
- Hot water can freeze faster than cold water under some conditions (also known as the Mpemba effect).
- You can die from drinking too much water (known as water intoxication).
- A leaky tap that drips at the rate of one drip per second can waste more than 11,000 litres per year.
- About 97% of the world’s water is salty or otherwise undrinkable. Another 2% is locked in ice caps and glaciers. That leaves just 1% for all of humanity’s needs — all its agricultural, residential, manufacturing, community, and personal needs.
Keep in mind that water is one of the most important aspects in our lives. Remember to drink sufficient water to stay healthy.
