Temperature

found several facts interesting as I read the articles including: how osmosis and salinity functions, how seawater cells move, how pH affects the ocean, how decomposition works in the environment, how upwelling stirs up nutrients, and how water temperature affects organisms. One of the interesting facts discusses why osmosis and salinity impact marine organisms. Osmosis relates to the amount of water that travels across cell membranes. During osmosis, the water travels from high concentration…

significant observations of the deep thermal regime, but the high geothermal gradients in the Paliza Canyon and E10 wells show some promise of quantifying temperatures of a geothermal reservoir at ~900 m depth that may be explained using a transient model for the flow of warm water at depth. 4.4.1 Geothermal gradient profiles and their projected temperatures at depth The constant geothermal gradient from the JP Water Wells is slightly…

Did you know that "insulation reduces average home heating and cooling costs by around 20%". Many parts of the country have changed in temperature that affects the comfort in homes and workplaces. Season to season, these temperatures drive people crazy. In cold weather, this means it keeps the warm air inside and in the hot weather, it prevents hot air from coming in. Insulation helps maintain comfort no matter where you are. The best types would be the ones that keep the hot air out in the…

The simple reaction between two substances (Mg and HCL) was performed to determine how different factors such as, temperature, and concentration effects the rate of reaction. There were noticeable differences while determining the effects of concentration of HCL on the rate of reaction. Increasing in the concentration of the HCL, bottom of the test tube became hotter; it’s an exothermic reaction because energy is being released during the reaction in the form of heat. Another, increasing in…

as Polydimethylsiloxane (PDMS) and Tetra ethoxy orthosilicate (TEOS) is synthesized. Transmittance of about 90-95 % is obtained in the visible region (400-700 nm) and the synthesized substrate show better thermal characteristics and withstands temperature upto 200 oC without any significant degradation. Characteristics such as transmittance (T), absorption (A), refractive index (n) and extinction coefficient (k) are also reported. Keywords: ); Flexible Polymer Substrate, Polydimethylsiloxane…

forming, if the colour has changed, if the temperature has changed, if the volume has changed, if it is giving out light and if there is a change in smell or taste. In a chemical reaction heat is either absorbed (endothermic reaction) or given out (exothermic reaction) (Houghton Mifflin Company, 2005). An exothermic reaction is a chemical reaction in which energy is released in the form of heat whereas endothermic reactions are reactions where the temperature…

the acetone and the unknown volatile liquid was determined by first taking 2mL of acetone and the unknown volatile liquid in a Erlenmeyer flask and heating it to the point where all the of the liquid is completely vaporized. The temperature is measured using a temperature probe from the MeasureNet system after being calibrated. The next step in determining the molecular weight of the two volatile liquids is to find the mass of acetone and unknown after the flask is heated by finding the…

Objective: To understand the function of an enzyme when it undergoes different conditions such as temperature, PH, and concentration of the enzyme. Introduction: In our lab “Enzyme Action” we were testing the enzyme reaction with different substrates. In our lab we tested 3 different enzymes and substrates to find out when they are at the highest potential. Enzymes are necessary for life because they keep our bodies chemical reactions at a normal pace. Enzymes have the ability to keep a human…

What is boiling point elevation? How might this have affected your results? Boiling point elevation is the event in which the boiling point of a liquid becomes higher because of an added compound. Ultimately, the boiling point of the solution obtains a higher boiling point than a pure solvent like water. For the lab that was conducted, the solvent that was used was tap water and that itself contained numerous minerals dissolved in it and a variety of chemicals. Boiling point elevation is…

Around the Great Lakes area and the majority of the Northeast temperatures are expected stay 30 degrees below average from the result of the “bomb cyclone”. A bomb cyclone occurs when the atmospheric pressure drops so quickly that the weather system increases rapidly in strength and brings high winds. The pressure has to drop at least 24 millibars in 24 hours to create a bomb cyclone and the storm can cause costal flooding and blizzard like conditions during the winter. The storm, Grayson,…
