2. How is the colour related to surface temperature of the star? The correlation between the surface temperature of a star and its colour is due to the phenomena known as black body radiation .A star is a black body‚where it aborbs all the radiation falling upon it.AS its temperatures gets hotter thanits surrounding‚the star radiates its on electromagnetic radiation‚known as black body radiation. This radiation is distributed unevenly but contionously through multiple wavelengths of the electromagnetic

changes in temperature expands the air inside of the basketball causing it to bounce higher. This experiment was decided by observations made while playing the sport basketball. It was observed that when a basketball is left in the sun and made warm‚ the ball bounces higher when dribbled than if left inside. Our assumed result was that an increase in temperature would cause an increase in air pressure causing the bounce of the basketball to increase. The independent variable was the temperature in which

Magnesium Metal. Another objective was determining the formula of the compound that results when Magnesium and Oxygen react. Theory: The purpose of this lab was to confirm the chemical formula of magnesium oxide by comparing the masses of pure magnesium solid prior to any reaction and magnesium oxide solid after a reaction between all of the magnesium and oxygen from the air when heated from a Bunsen burner in a crucible. Using molar masses of both magnesium and oxygen‚ an expected percent composition

Organic molecules are the molecules of life that include Carbon and Hydrogen. Organic molecules consist of four important classes which are lipids‚ carbohydrates‚ proteins and nucleic acids. The most important organic molecule is Carbon. Carbon can form with up to 4 different atoms to form chains‚ rings and branches. Organic molecules also contain monomers. Monomers are the “building blocks” of macromolecules. Macromolecules are made up by chains of monomers‚ these are called polymers. Continuing

peripheral IVs at seventy-two hours. The aim of these policies is to prevent phlebitis. The purpose of this paper is to examine the evidence for this practice to determine if is necessary. The PICO Question is: is there any difference in the rate of phlebitis when an IV is allowed to remain longer than 72 hours if there are no problems; or discontinued after 72 hours and restarted. Six research studies were found using CINAHL and Medline using the key words “phlebitis” and “peripheral IVs”. The

Argon is obviously omitted because it doesn’t form an oxide. Hypothesis This experiment will be investigating the following properties of the oxides of group

Rotary kiln is a machine whose working temperature can reach the temperature to calcine superfine kaolin. At present the rotary kiln technology in our country is mature and advanced‚ which represents the development direction of calcination technology of superfine kaolin. However‚ the decomposition rate of rotary kiln is not high enough‚ we should impove the decomposition rate of rotary kiln. Do you know how? Decomposition rate of kiln showed that the extent of the carbonate in the raw material

Ivan IV (The Terrible) Pretend that the greatest leader to ever rule your country wanted to resign. You would want him to come back‚ but the price of that is to give him complete and absolute power. Would you pay that price? The people of Russia did‚ and as soon as Ivan IV came back‚ he killed them by the thousands. Ivan Vasilyevich began as Tsar at the age of 16. He was a great ruler for the first part of his life. He unified‚ and vastly improved his country‚ creating a more modern government

Effects of Temperature‚ pH‚ Enzyme Concentration‚ and Substrate Concentration on Enzymatic Activity INTRODUCTION Enzymes‚ proteins that act as catalysts‚ are the most important type of protein[1]. Catalysts speed up chemical reactions and can go without being used up or changed [3] Without enzymes‚ the biochemical reactions that take place will react too slowly to keep up with the metabolic needs and the life functions of organisms. Catecholase is a reaction between oxygen and catechol
