Expansion Most substances expand when they are heated and contract when they are cooled. Heat causes expansion because it increases the vibrations of the atoms or molecules of a substance. The increased vibration forces the atoms or molecules further apart and the substance becomes larger, i.e. expands. When the substance cools down, it becomes smaller, i.e. contracts. Expansion and Contraction of Solids Solids expand in all directions when heated but the amount of expansion is usually

better known as the dancing lights. Aurora Borealis is one of the most exotic and difficult concepts in astronomy. The colours of aurora borealis are fomed by the collision of gas particles in the Earth’s atmosphere with charged electrons from the sun’s atmosphere. So, today I will inform you about the different types of gas particles that are involved in the production of the colours of aurora borealis. I obtained the all the information about Aurora Borealis from the book entitled The Amazing Northern

PROCEDURE | RESULTS | DOCUMENTATION | DISCUSSION OF RESULTS | CONCLUSION | 1. Weigh out a 1 gm sample of impure acetanilide and place it in an Erlenmeyer flask.2. Add 40 ml of water and a small amount of decolorizing activated charcoal to the flask.3. Heat the flask.4. Continue heating at boiling temperature for 2 to 3 minutes or until all the solid dissolves. More boiling water may be added if the original quantity does not dissolve all the acetanilide.5 .Prepare a fluted filter paper or ask for

variety of atoms (e.g. carbon dioxide). A gas mixture would contain a variety of pure gases much like the air. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles. This separation usually makes a colorless gas invisible to the human observer. The interaction of gas particles in the presence of electric and gravitational fields are considered negligible as indicated by the constant velocity vectors in the image. The gaseous state of matter is
