We’re gradually resuming more services in our branches. For health and safety reasons, access to installations in KidsStops and Discovery Zones is limited.

This week, a TPL Kids visitor has wondered: When water boils, why does it boil?
In science class, you may have learned that water boils at 100 celsius at sea level. However, for every 500 feet above sea level the boiling point of water decreases by 1 farenheit.
According to Wired, the science behind boiling water is that molecules made up of three atoms (two hydrogen and one oxygen) are moving around because of thermal motion or heat. It undergoes a physical change as the molecules of water break, changing from a liquid to a gas.
So the next time you're preparing some hot chocolate, consider how much better it tastes using hot water than cold water.
