Ice Facts

Did you know?

Liquid water changes to ice when it is cooled below 0 °C (273.15 K, 32 °F) at standard atmospheric pressure.

If all the ice on earth melted, sea level all over the world would rise by about 70 metres.

Ice is transparent to visible light.

Ice occurs naturally as snowflakes, hail, icicles, glaciers, pack ice, and polar ice caps.

Ice is less dense than water which is why ice-cubes and icebergs float.

The first refrigerators were known as iceboxes, because they had a block of ice in them to provide the cooling effect.

More than 2,000 years ago in Iran, Persian engineers were able to store ice in the desert throughout the summer.

It would be possible to start a fire with ice if it was carved into a lens shape and then used to focus the sun's rays onto kindling.
