Abstract The goal of this experiment is to understand the theory behind bomb calorimetry and use it to determine the enthalpy of combustion of naphthalene. First, the bomb calorimeter was standardized using benzoic acid and the average heat capacity of the bomb calorimeter was calculated to be 10.60.3205 kJ/K. From that, the average m, and f were found to be -526615.66kJ/mol, with a percent difference of 3.31%, -52600.0015kJ/mol with a percent difference of 1.99%, and -185.50.0013kJ/mol with a…

Aim - To investigate how the temperature of water affects how salt dissolves. Prediction - If the temperature is warmer, the more solute will dissolve in the solude. Variables - which variables are you going to: Independent Variable - The temperature of the water. Dependent variable - How much salt is needed to not dissolve in water. Controlled variables - The materials. How will you make it a fair test? - Using a machine to weight the salt and heat the water.…

Both temperatures must be within a certain range, and neither should drop below the minimum acceptable temperature until the sealant is fully cured. The ideal temperature for applying sealcoating is around 70 degrees Fahrenheit, and few contractors will attempt to apply sealants if the temperature is below 50 degrees Fahrenheit. Higher temperatures mean that the movement of the water molecules in the sealant are moving faster, which speeds evaporation. However, if the temperatures are too high…

The effect of temperature on the rate of reaction on Enzyme reaction Introduction: This experiment will investigate the effect of temperature on the rate of reaction of the enzyme catalase. The biological catalyst called enzymes increase the rate of reaction without themselves being chemically changed. Enzymes are globular proteins folded into a complex 3-dimensional shape that contains a special surface area called the active site where a specific substrate binds structurally and chemically.…

and boils at temperatures that are rather easy to generate, it is the most likely substance on which to base a temperature scale. On the Fahrenheit scale, the freezing point of water is 32 degrees and the boiling point is 212 degrees. The Celsius temperature scale is part of the "metric system" of measurement (SI) and is used throughout the world. The freezing point of water is 0 degrees and the boiling point is 100 degrees on the Celsius temperature scale. Kelvin, like other temperature…

Fahrenheit, commonly known as a unit of measurement for temperature which is regarded as an official scale in the modern society of the United States and other Caribbean countries. It is the first standardised temperatures scale which was adopted globally in the seventeenth century. This great invention is named after a German science instrument maker, Gabriel Fahrenheit (1686- 1736). His invention has revolutionised the design of thermometer in 1724 when he conducted the first mercury…

Summary The study tested if EKG and core temperature would increase when you placed ice (down your back and in your hand) further from your body’s core. The outcome of the study was that your bodies EKG and core temperature decreased when placed further away from your body’s core. The significance of the study is that it shows people that if you place colder objects further from the core of your body, your vital signs are more likely to decrease, furthermore, the study presents an interesting…

this doesn’t make any sense. How could water of higher temperature reach freezing temperature quicker than water of colder temperature? Water freezes when it’s molecules lose energy and slow down enough to stick together, forming ice. The molecules of water of high temperature have more energy the molecules in the colder water. So, provided the temperature of the freezer is uniform, it should take longer for the molecules in the higher temperature water to slow down enough to stick together. In…

The temperature that the solid compound begins to melt is known as the point of condensation and the point that the solid has completely liquefied is known as the melting point/temperature. Solubility is simply the ability of a solid compound to completely diffuse/dissociate in an aqueous solution. For example, when you add sugar to a glass of water…

“the state of mind that expresses satisfaction with the surrounding environment.” This definition highlights subjective and psychological dimension of thermal comfort. 2.1.1 The heat balance In order to maintain a constant internal human body temperature, the heat which is continuously produced by the body must be dissipated to the environment (Jiao, 2010). From the energy exchange…
