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

Types of Dispersed Systems Different observations were made for the three solutions that were placed in three different test tubes. The solutions used were filtered NaCl solution, cooked starch, and uncooked starch solution. Observations were assessed using a light test (the beam of a pen light). The test tubes were viewed

HEAT 4.1 UNDERSTANDING THERMAL EQUILIBRIUM 1. Define: The measure of the degree of hotness of an object. (a) Temperature Measured in SI unit Kelvin, K A hot object is at a higher temperature than a cold object. Form of energy, measured in Joules, J (b) Heat Heat is transferred from hotter object (higher temperature) to colder object (lower temperature) When an object is heated, it will absorb heat energy and the temperature will increase. When an object is cooled, it will release heat energy and

consumption was high per gallon of gas and the miles you get when you drive for a certain amount of miles. Was that the Co2 of gas consumption went down just a little bit but not a lot due to how many miles you drive your car and how long you drive it to get a full tank of gas to the E sign but the miles of gas per gallon will tell you the price that you will be spending each time when you fill up your tank if it needs a whole tank of gas or a half of tank that needs less gas and Co2 consumption I got my
