Properties of water notes
Water is two atoms one hydrogen and two oxygen, an atom is the smallest unit of matter that retains its properties. Atoms consist of protons, electrons, and neutrons, protons have a positive charge, electrons have negative charge , and neutrons are neutrally charged atoms.Atoms are usually neutrally charged atoms because the number of protons and electrons are even.
A polar molecule 2 H atoms and one O atom a water molecule, H shares a electron with O.
Hydrogen Bonding the week attraction between the weekly positive hydrogen atoms and the weakly negative oxygen atoms of a different molecule.
Surface tension
water is a universal solvent it's attracted to other molecules. The attraction helps to create a "film" on the surface of bodies of water.
States of water
Earth is the only planet in the solar system where water is found in liquid form.
Effect of heat on water
one calorie is equal to the amount of heat needed to raise the temperature of 1 gram of water by 1c. High latent heat of fusion= a lot of heat is released when water freezes and a lot of heat is absorbed when ice melts.
what is density?
Density is a physical property of a substance that describes the degree of compactness of a substance.
