This animation explores water as a solid, liquid and gas. The water molecules stay the same, but they behave differently as they change from one form to another.
In general covalent bonds determine: molecular shape, bond energies, chemical properties, while intermolecular forces (non-covalent bonds) influence the physical properties of liquids and solids. The kinetic molecular theory of gases gives a reasonably accurate description of the behavior of gases.
Find out what particle arrangements and movements are in solids, liquids, and gases in this BBC Bitesize KS3 physics guide.
Water molecules consist of one atom of oxygen (red) bonded to two atoms of hydrogen (black), hence H2O. The oxygen tends to hog the electrons, making water a polar molecule. This polarity causes the molecules to clump together, which accounts for the peculiar attributes of water.
22 cze 2014 · Water is the only common substance that is naturally found as a solid, liquid or gas. Solids, liquids and gases are known as states of matter. Before we look at why things are called solids ...
Because water seems so ubiquitous, many people are unaware of the unusual and unique properties of water, including: Boiling Point and Freezing Point. Surface Tension, Heat of Vaporization, and Vapor Pressure. Viscosity and Cohesion.
12 kwi 2010 · Solids, liquids and gases are three states of matter. In solids, the particles are tightly packed together. In liquids, the particles have more movement, while in gases, they are spread out. Particles in chemistry can be atoms, ions or molecules.
