The solar system consists of the Sun and 9 planets revolving around it in different orbits. The statistics of the sun and the planets are given below : SUN Age : About 5 Billion years Distance : 149.8 Million Kms Diameter : 1‚38‚400 Kms. Photosphere temperature : 5‚770 K Core temperature : 150‚000‚000 K Absolute visual magnitude : 4.75 Rotation (as seen from the earth at the equator) : 25.38 days Rotation (near the poles) : 33 days The sun consists of 71% of Hydrogen‚ 26.5% Helium and

* Large molecules sometimes composed of a large number of repeating subunits * Four major classes: Carbohydrates (made of simple sugar/glucose)‚ Lipids (Glycerol and Fatty Acids)‚ Proteins (Amino Acids) and Nucleic Acids (Nucleotides) * Condensation reaction/dehydration synthesis: a reaction that creates a covalent bond between two interacting subunits. Removal of H from one functional group and an OH from the other‚ and the H come together to form a water molecule (H2O). Anabolic process

Distillation Column In the the Chemical Enginneering Lab at CSULB there is a total reflux eight-stage glass binary distillation column at atmospheric pressure. The components that need to be separated are 1-propanol and 2-propanol. These two compounds are isomers with fairly close boiling points. They are separated based on their physical propertis. With the

Meiosis I Prophase I: - nuclear membrane dissolves * centrioles move to poles * spindle fibres forming * DNA has been replicated and forms chromosomes made of 2 identical chromatids * Homologous chromosomes line up to form a bivalent‚ 2 chromosomes or 4 chromatids (TETRAD)‚ this process is called SYNAPSIS * Where chromatids overlap is called a CHIASMATA‚ and it allows for CROSSING OVER of genetic information between chromosomes Metaphase I: - homologous chromosomes

rain‚ strong winds and a variety of stormy cumulus clouds; all of which associated with rapidly rising warm air and cloud forming condensation where the warm air meets colder air. At the warm front‚ at the rear of the depression‚ the warm air is still essentially being displaced but the weather here is milder since the clouds formed are more the result of condensation at the meeting of cold and warm air‚ as opposed to the warm air rapidly rising. A depression is formed where these two fronts meet

Name: kamal subedi Student ID: 21354 Email: ksubedi354@wuv.edu Book Review: science- Definitive guide‚ Quercus publishing This is the fine book of science by Bizony Piers. Piers tries to touch all the aspect of sciences and give the briefly and somewhere even detail overview on every beats and pieces of all the aspects of science. Each part starts with very good scientific background with his research and clear definition before moving on to a more in-depth exploration of its coverage. Piers Bizony

AP Chemistry Chapter 13 Outline Condensed phases: the liquid and solid phases; phases in which particles interact strongly. 13.1 Gas condensed when cooled and compressed. In the liquid state the forces of attraction among particles are great enough that disordered clustering occurs. It is hard to compress a liquid. Liquids diffuse into other liquids with which they are misicible. The natural diffusion rate is slow at normal temperatures. Cooling a liquid lowers its molecular kinetic energy

THE REFRIGERATION SYSTEM AN INTRODUCTION TO REFRIGERATION APPLICATION NOTE BASIC REFRIGERATION PRINCIPLES If you were to place a hot cup of coffee on a table and leave it for a while‚ the heat in the coffee would be transferred to the materials in contact with the coffee‚ i.e. the cup‚ the table and the surrounding air. As the heat is transferred‚ the coffee in time cools. Using the same principle‚ refrigeration works by removing heat from a product and transferring that heat to the outside air
