Fun Fact Friday: Ice
Why Does Ice Float In Water?
Ice is made up of water molecules that are held together by hydrogen bonds. However, the hydrogen bonds in ice are stronger than the hydrogen bonds in water. This is because the water molecules in ice are arranged in a regular pattern, and hydrogen bonds can form between the molecules in this regular pattern. Hydrogen bonds are much weaker than the other forces that hold molecules together, so water molecules can easily break away from each other.
The stronger hydrogen bonds in ice make it harder for the water molecules to break away from each other. This means that ice is less dense than water, and so it floats on top of the water.
How Does Ice Cubes Melt?
When water freezes, it forms crystals of ice that are arranged in a regular pattern. However, when ice is placed in warmer conditions, the water molecules begin to move around more. As they bump into each other, they break apart the regular crystal structure of the ice.
At the same time, the warmer temperatures cause the ice to absorb energy from its surroundings. This energy helps to break the bonds between water molecules, causing them to change from a solid to a liquid form. The result is melting ice cubes. While this process may seem simple, it is a complex chemical reaction that requires both heat and energy.
