Why is water so different from other molecules? When it's frozen and a solid piece of ice it is less dense than water. When you boil water, it's boiling point is really high, higher than other liquids. And water can dissolve many substances, like sugar, salt, stains and oils! What is happening here? In fact you can sit in a hot tub, watch the steam come off the top of the water and sip an ice cold drink, the ice cubes bobbing along the top of your glass. All this, all at the same time! To begin explaining this I must remind you that the water molecule is kind of like a magnet (dipole) with a positive end and a negative end. The molecule is happy because of the strong attraction between the hydrogen bonds and the oxygen bonds. Breaking up is hard to do.... Because the bonds are so reluctant to let go, trying to boil water takes longer, and freezing water causes those bonds to lock tight. When water freezes the hydrogen bonds create "space" or "holes", this is why your ice floats in a glass of water. The ice is full of small pockets of "air". Larger volume, less dense. When water boils, the molecules move faster and faster. The energy between the molecules increases (kinetic energy) and the bonds begin to break. The fast speeds, bonds breaking, throws broken molecules into the air. When the hydrogen bonds break this causes hydrogen to escape into the air, and oxygen escapes into the air which equals steam, or broken up water molecules spinning and careening out into the space around the hot pot. Water is unusual...that's why we love it! Seek it! Want to know more about it! Though, it is kind of weird....

Mrs. TaylorI love science! Everything about the world is interesting and never boring. I love to study plants, animals, insects, and people. My favorite subjects are my students who are the most unique organisms on the planet! Categories |
