project is to demonstrate how water temperature affects the dissolving of sugar in liquid. Everything in our universe is made up of particles which are in constant motion. In a solid state particles move the slowest while in a liquid state particles move the fastest. Under the right conditions‚ solid particles (the solute) when mixed in liquid (the solvent) can form a solution. This occurrence is called dissolving. I wanted to answer the question; does the temperature of water affect the speed at which

Concentration Camps Can you imagine being a Jew and living during the Holocaust? One day you are at your house doing your normal routine‚ and the next minute you are being loaded onto a cattle truck. You would be taken to the most horrible place imaginable. A concentration camp. A concentration camp was where people were kept without trial. They were kept in terrible conditions and had no rights. Concentration camps had forced labor‚ mistreatment‚ starvation‚ disease‚ and random executions. Concentration

The Effect of Temperature on Solubility By Aviraj Singh Rogers 2 Background: The solubility of most solid substances is generally said to increase as the temperature of the solvent increases. However‚ some substances‚ such as ytterbium sulfate‚ do the opposite. This can be explained through the Second Law of Thermodynamics which states that “in all energy exchanges‚ if no energy enters or leaves the system‚ the potential energy of the state will always be less than that of the initial state”

Resting metabolic rate can vary with age independently from body mass changes in the Colorado potato beetle‚ Leptinotarsa decemlineata. Abstract A study was done by Saija Pironine‚ leena Lindstrom‚ and Anne Lyytinen in the Journal of Insect Physiology‚ to investigate the age dependence of resting metabolic rate in Colorado potato beetle (Leptinotarsadecemlineata) from adult emergence until age 10 days. In their hypothesis they expected to see a bell shaped pattern in metabolic rate with adult age

A concentration camp was a prison where the many Jews‚ gypsies‚ homosexuals‚ disabled‚ Poles and Jehovah ’s Witnesses were sent by the Nazi regime. It is estimated that the Nazi party created and controlled 15‚000 different camps which were found in several countries. These countries included Germany‚ France‚ Holland‚ Norway‚ Poland‚ Russia‚ Yugoslavia‚ Austria‚ Belgium‚ Czechoslovakia‚ Finland‚ Italy‚ Latvia‚ Lithuania and Estonia. Most of the camps were constructed near railways which was mainly

experiment‚ equilibrium will be examines in the reaction beteween the iron (III) ion and the thiocyanate ion: Fe3+ (aq) + SCN- (aq) ------ FeSCN2+ (aq) The FeSCN2+ complex ion has a blood red color while the iron and the thiocyanate ion are colorless. Therefore‚ the shift in the reaction can followed by noting a change in the intensity of the clood red color‚ which indicates a change in the concentration of the complex ion FeSCN2+. If the reaction shifts to the right‚ the blood red color will get

CONCENTRATION AND DILUTION Physiology 1‚ Las Positas College Name: In science‚ concentration is a measure of the number of particles (solutes) in a given volume. If one room has 100 people in it‚ and a room of equal size has 50 people‚ one can say that the concentration of people in one room is twice that of the other. Quite simple‚ isn’t it? On a molecular level‚ consider whether you put one lump or two of sugar‚ or no sugar at all‚ in your coffee. If you use two lumps‚ you prefer twice
