Temperature

Temperature and pH will affect enzyme function by increasing the reaction rate because as temperature increase so is the rate of reaction and extremely high or low pH will result in the denatured by decreasing the reaction rate. The function of this experiment was to investigate the influence of the concentration of enzyme on the rate of reaction. The rate of reaction in this experiment was subjected by the amount of Guaiacol, H2O2, Extracts, and Buffer (pH5). The reaction rates with different…

broke? Or have you ever found a rubber band in the hot sun and asked yourself why it snaps easier when the band is hot? This happens because the molecule chains break. Temperature affects the elasticity of a rubber band. Temperature is the measurement of hot or cold. It is also the measurement of how fast molecules are moving. Temperature is important in all fields of natural science, such as physics, geology, chemistry, space science, medicine, and biology, it is also used in our everyday…

adiabatic reaction temperature of the pyro-oxidation zone. (Barman, Ghosh, and De) also considered the formation of tar and methane reforming reaction in the pyro-Oxidation zone. The adiabatic reaction temperature is found out by considering heat balance in the zone. Enthalpy of reactants + Heat loss=Enthalpy of products = The heat loss from the oxidation zone was found to be around 10% by Chern(cite). TO is the temperature of biomass fed to the gasifier and Ta is the temperature of…

The purpose of this experiment was to find the affect of salt on the temperature of boiling water. Each time I added more salt the temperature was higher than the last one. From the data I collected it shows that the more salt you add the higher the temperature. If you add salt to boiling water the temperature will increase. The data 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…

Experiment 15.2 Purpose: To show temperature effects on reactions and Le Chatelier’s principle. Materials: 2 test tubes, 2 eyedroppers, 2 beakers, 2 small cups, Clear ammonia solution, White Vinegar, Flame or stove, Pot, Water, Ice, a few leaves of red cabbage, and safety goggles. Question: How does equilibrium work with respect to temperature and concentration? Hypothesis: Depending on whether the reaction is endo-thermic or exothermic the equilibrium will shift to one side, this is also true…

Did you know, if you add salt or ice to anything cold the temperature drops? In my experiment, I wanted to find out if different materials impact the rate of ice melting. Before starting this experiment, I know sugar and salt dissolve in water and sand turns into mud. I predict that the results of this experiment will be that the sugar and salt will make the ice melt at a faster rate than the sand because sugar and salt dissolve in water and sand does not. To complete this experiment I will…

body temperature regulation. Thermoregulation is controlled by the autonomic nervous system (ANS), which is a vastly complex, multifaceted neural system that sustains the internal homeostasis of the human body (Chawla, 2013). Within the ANS, is the sympathic nervous system (SNS) and the parasympathetic nervous system (PSNS). Predominately, thermoregulation is controlled by the SNS with little contribution from the PSNS (Chawla, 2013). Although the human body experiences various temperature…

Benedict’s solution has been added to Starch solution at different temperatures. The tests were completed three times each temperature to find an average. This graph resembles the results from the table above. Making it obvious to observe the unexpected results as the temperatures 2, 20 and 27 remained blue then 37 degrees changed to green and 60 degrees changed to orange. This experiment was carried out to investigate how temperature has an affect on enzyme activity. This was done by preparing…

Effect of temperature on the change of wood components can be described as follows: during drying in the interval 40°-90°C, some minor chemical changes probably start to occur, most likely certain extractives. For high temperature drying in the interval 90°-150°C, the changes for all wood components are more obvious. At temperatures of 150°-250°C, major changes in the wood components occur, both degradation and modification, and at temperatures above 250C carbonization processes generally occur…

especially in taking their child’s temperature. Sometimes, their temperature soars and eventually normalizes, but sometimes it can go up and down, only to go up again. So many parents wonder where the best place to take temperature may be in order to get an accurate reading. But wherever the thermometer is placed, it is important to take the temperature properly and to monitor its pattern throughout the day. Part 1: What Is the Best Place to Take Temperature? Body temperature can be taken from…
