Abstract: The purpose of this lab was to show the different absorption and emission rates of three different substances. Radiation laws, albedo, and specific heat are all reasons why this is achievable. An agreed upon hypothesis is that the sand will absorb the most heat due to the number of molecules, the moss will absorb the second most because it doesn't have as many molecules as sand, but it has more than water, which isn’t as complex. To complete this experiment, you need three beakers of…

OVERVIEW Four ablations will be done in ex vivo bovine for each flow rate. There will be three different flow rates: 0 mL/min, 860 mL/min, and 1000 mL/min. These flow rate were chosen based on hepatic flow rates of humans in the supine position (Brown et al. 1989; Leen et al. 1992). Each ablation will be performed at 40 watts for 2 minutes for a total of 12 ablations. The average area of a 30ºC and 50 ºC contour at the end of the ablation will be used to characterize the size of the ablation…

The freezing point of the cyclohexanol was about 17.7°C, and the freezing point for the unknown solute mixed into the cyclohexanol was about 6.2°C. So the approximate change in temperature of the two freezing points was about 11.5°C. With this calculated information, the found molar mass of the unknown solute B was about 278.4g/mol, which is close to given molar mass of octadecanol. Conclusion- This lab allowed us to determine the molar mass of the unknown solute B by finding the difference in…

the cup. 12)Carefully place your egg in the cup and allow it to sit for 24 hours. 13)Hypothesize what you think will happen to the size of the egg. Day 3: 1)Carefully remove the egg from the cup and place it in the weigh boat tray. 2)Pour the liquid down sink and clean out beaker with soap and water. 3) Observe the appearance of the egg and record observations in a data table as after egg was placed in syrup. 4)Measure the mass of the egg in grams. Record this number in a data table.…

Chosen Topic: Hydraulic fracturing Description: Hydraulic fracturing, or "fracking," is a mechanical procedure that utilizations liquid strain to discharge amounts of oil or natural gas from far beneath the world's surface. Amid usual penetrating, mechanical methods of extraction of oil and gas from open subterranean supplies and gather it at the surface. Fracking includes the high-weight infusion of artificially treated water and sand into shale shake, which separates the shale and discharges…

Analysis Sink An object that is dipped into the liquid will sink if the weight of the object is greater than the style up. At the time the egg is inserted in the water not filled salt then the eggs will sink because of the eggs is greater than the density of water. Then salt water 1-2 a spoon and stir in the eggs slowly, still also sank because of the eggs is still greater than the density of water. Drift An object that is dipped into the liquid will float if heavy objects are similar in…

"Economic and environmental aspects of Fracking - Fracking is an economically beneficial and essential process for oil companies. Fracking is a process of drilling and injecting fluid into ground at a high pressure to fracture shale rocks to release Hydrocarbons, but it has raised certain environmental concerns that that have burdened oil companies to overlook at the processes they are using to extract hydrocarbons. Certain concerns about Fracking are: Hydraulic fracking is quenching the water…

collected shows that my hypothesis was correct because the average number of the different amounts of salt was higher than the last one. Water boils when the molecules are able to overcome the vapor pressure of the surrounding air to move from the liquid phase to the gas phase. With that being said when you add salt that increase the amount of heat needed for water to make the transition( chemistryabouteducation). The more salt you add to water, the more you raise the boiling point. For control…

Everyone knows the importance that drinking milk has on developing strong bones and muscles. There's another drink, however, that's even more important for a healthy body that doesn't get as much attention: water. Every part of the body needs water, including cells, skin and vital organs. Water must be continually replaced as it is lost through sweating, breathing. digestion and urination. Not replacing this necessary component of the body has serious consequences. As the video explains, the…

Tips For Replacing Your Vehicle’s Serpentine Belt While many drivers know that they need to do things like change their vehicle’s oil and air filters, some other parts of the car often are ignored. One part in particular that can wear down is the vehicle’s serpentine belt. If this part breaks while you’re driving, your car will be unable to run and you’ll need to have it repaired immediately. Thankfully, it’s easy to replace a serpentine belt when you notice wear to prevent this from happening.…
