Activation energy

Summary: This lab involves three separate experiments. Before you conduct any of them, however, you should put on goggles and aprons, as well as gloves. For the first part, place the FeCl3 solution into the watch glass, and add a few drops of KSCN. Record any changes you might see. Then, ask Dr. Karraker to add a KSCN crystal to the watch glass, and again record any changes. Add drops of Na3PO3 and record any changes, then add FeCl3 and record those changes too. After you are done, dump the…

the summer, and to be able to heat food and treat our water? - This all thanks to the sun - Without the sun, we all would be dead, it gives us light, heat and energy to heat up the Earth - Most of the energy stays inside of the sun because of its gravitational pull, and all small amounts leave the surface in the form of radiant energy Type of star: Age: Yellow dwarf 4.5 Billion Years Diameter: 1,392,684 km Mass: 1.99 × 10^30 kg (333,060 Earths) Surface Temperature: 10,000°C 5,600 °C…

When sea levels and temperatures rise as a result of climate change, how will plants react? In this experiment, the growth of Wisconsin Fast Plants (WFPs) will be tested when temperature and waterlogging are added to twelve WFP chambers. The question that will be attempted to answer is: How do factors of climate change—water and temperature stress—affect the growth of WFPs? Waterlogging is the act of adding too much water and temperature stress is extreme temperatures. This question is being…

also discuss these. Calories provide our bodies with energy during the hyper-metabolic and catabolic state which the body is in when a wound is present. The addition of more calories helps for synthesis of new cells. Sufficient calories help to spare protein for its critical role of tissue repair and not for energy. The dietitian will help to ensure that the patient consumes enough calories for their resting metabolic rate and for the energy needed for their present medical state so that…

Where M.R is the moisture loss ratio, M_0 is the initial moisture content, M_t is the moisture content at time t, M_e is the equilibrium moisture content, t is time (minutes), and a, b, c, and k are constants. For the effectiveness of diffusivity, Fick’s equation was used (5) to estimate the dehydration kinetic of different osmotic conditions. M.R=((M_t-M_e)/(M_0-M_e ))=〖8/π^2 e〗^((-(π^2 Dt)/(4L^2 )) ) …(5) Where D is the effective diffusivity, and L is the length of the (cubical) sample.…

Homework has several benefits and is important to a child’s success. Specifically, homework can be beneficial to a student’s academic achievements. The use of daily homework assignments can help students better obtain information which has previously been taught. A student who is introduced to an idea during class, then given an assignment, allows them to practice and grasp a better understanding of the concept. The aid provided from homework then opens up more time for further learning in the…

Another way to produce heat is the specific dynamic action, the thermic effect of food. The added heat after eating is caused by the energy used to breakdown molecules and synthesizing proteins, this result also varies on what type of food is being broken…

Jack Shumski Professor Verdecia Fire Technology 102 20 November 2017 Physical Principle of a Catapult to The Fire Service A catapult does many different things that relate to different physical principles. The big physical principle of the catapult is it uses Newton's first, second and third law. In fact, also all three of Newton's law can relate a lot to the fire service and how it operates. This essay will relate the physical principle of the catapult, to Newton's laws and how it relates to…

Crucible Essay By definition, a crucible is a ceramic or metal container in which metals or other substances may be melted or subjected to very high temperatures. Everybody faces crucibles everyday in their life in which they are faced with a decision they have to make. One day this could be a minor crucible and another could be a major crucible. On April 19, 2017, Good Friday,I faced the biggest crucible so far. It turned out this Good Friday was the worst Friday of my life. Like any other…

Adhikary, Sujit. “Vermicompost, the story of organic gold: A review.” Scientific Research, Vol. 3, No. 7. Scientific Research Publishing Inc., [circa 2014], cesantaclara.ucanr.edu/files/235723. In the online article, “Vermicompost, the story of organic gold: A review,” the author dives into the benefits of vermicomposting by explaining the basics of the concept, and then digs deeper into the values and assets of this “organic gold.” The article states how vermicomposting not only gets rid of…
