know that 250‚000 life organisms die a year because of the ocean temperatures rising? One reason the ocean temperature surges is because of the greenhouse gas. As greenhouse gas (a gas from the greenhouse effect that benefits by absorbing carbon dioxide‚ chlorofluorocarbons‚ and infrared radiation; different kinds of elements and gases) collects together and increases‚ it traps more heat energy into the Earth‚ and making the temperature rise. Another way this is caused is when the warmer ocean water

MIP experiment on the melting temperature of different polymers 8.1 Compare and comment on the results obtained. LDPE has the lowest average melting temperature (103.6°C) out of the 4 polymers. It is because LDPE is a linear polymer that has a branched structure which is able to expel the applied heat faster through the “branches” and melt faster. HPDE has the second lowest average melting temperature (139.5°C) out of the 4 polymers. Unlike LDPE‚ HDPE does not have a branched structure and the

IB Chemistry Lab Report Design Example— Effect of Temperature on Solubility of Potassium Chloride in Water Research question How does temperature affect the solubility of potassium chloride in water? Hypothesis As the temperature of water increases‚ the particles of solid Potassium chloride‚ KCl‚ which are absorbing energy from its surrounding‚ start moving more easily between the solution and its solid state because. According to the second law of thermodynamics‚ the particles will

Temperature affects enzymes in two different ways: by increasing the kinetic motion of molecules‚ changing the rate of collisions between them and the hydrogen bonds it’s 3D structure(D. Fraser‚ 55). There is a specific temperature for every enzyme where activity is maximized‚ and also where an enzyme becomes denatured. An enzyme becomes denatured when it is heated at extreme temperature; the excessive kinetic movement of the amino acid begins

combined with baking soda. Then the temperature was taken‚ and finally calcium chloride was added‚ which formed a chemical reaction. Our lab question was how does the amount of calcium chloride affect the temperature of the product? We chose our independant variable to be the amount of calcium chloride added to the water/baking soda mixture. We had the dependant variable be the ending temperature. My hypothesis is IF we add more calcium chloride‚ THEN the temperature of the product will rise‚ BECAUSE

Is There A Relationship Between Body Temperature and Heart Rate? Statement of Research Question: This study sets out to determine whether there exists a difference in the average body temperature between males and females. Furthermore‚ the study aims to determine whether an increase in heart rate corresponds with an increase in body temperature. Data Collection: The data was obtained from the article “What’s Normal? -- Temperature‚ Gender‚ and Heart Rate” (Shoemaker‚ Allen 1996) as found in

rate. The hypothesis also proposed that as temperature increases the speed of the reaction would decrease‚ this is evidenced in graph 7 which shows a negative decrease in time as the temperature of the solution increases. This decrease can be modelled by the exponential formula T=12.9e-0.0249t. The raw data collected suggests that directly increasing the concentration of potassium iodate decreases
