Thermodynamic temperature

I am working for Parr Instrument Company, a company that manufacture and sale laboratory instruments include calorimeter. Calorimeter is a machine that used to determine the potential calorie of a test object. With the breakthrough of newly developed technology, Parr Instrument Company can now reduce the size of the calorimeter from a photocopy machine to the size of a laptop. Therefore, I will introduce a new product GV, a Personal Calorimeter. Personal Calorimeter is a machine that can quickly…

During my time at Electric Boat, I was one of two lead engineers assigned to refurbish a damaged chilled water pump on a nuclear submarine. Neither the requisite spare part nor a new pump was available and the vendor had quoted approximately $500,000 and 6 months for the replacement part. When the Navy had determined that the repair was beyond their capability, the pump was shipped to us. We developed the concept of machining out a small teardrop shape from the damaged impeller and pressing in…

at room temperature (21 - 25 °C), and keep the last one in a refrigerator at 0°C. Monitor the temperatures using a thermometer. When each sample reaches its specific temperature, slowly place a marble on top of its surface, and time how long it takes to reach the lower surface of the beaker. Record the temperature and time readings in a table. The more time the marble takes to reach the lower surface, the more viscous the honey is. Using the values in the table, plot a graph of temperature/°C…

How important is work in today’s society? Imagine a world without work, a world in which nothing would get accomplished, now imagine a world in which everyone enjoyed work, and accomplished countless tasks every day. There has to be a happy medium. In order for the world to be successful work is a necessity, everyone has their own attitude toward work and the exertion level they are willing to put in. My first observation leads me into my backyard where I observe my father meticulously picking…

Most people envision their dream home as a spacious home with character, charm, and plenty of room for a couple of kids to roam freely. A home with a wraparound porch with an attached swing to watch a golden retriever playing on the front lawn. A home with a white picket fence leading straight to the heart of the house that’s lined with multicolored pansies. Not to mention rooms for every occasion filled with useless objects, like a massive dining room used only for huge Thanksgiving feasts…

Vapour diffusion retarders and air barriers are designed to keep a building healthy and strong by preventing moisture infiltration, neutralizing differences in air pressure and preventing heat exchange. Each performs a different function although some materials serve as both an air barrier and a vapour retarder. The Difference Between Air Barriers and Vapour Retarders Architects, engineers and others involved in building science research and construction examine the way that both air and…

Metal is known as a form of cool roofing, which is because it resists penetration from UV rays, and actually deflects it away from your home. It will keep the temperature inside cool in the summer, which will reduce how much you need to use your HVAC system. You May Be Eligible For A Tax Credit Since the metal roofing material will be an energy efficient one, it means you could qualify for a tax credit on your federal…

Thus, in the equation for the enthalpy of combustion of the alcohol Q=mc∆θ, we need to keep the ‘m’ (i.e. mass of the alcohol burned) constant, as all other parameters other than the change in temperature (∆θ) in this equation need to be kept constant to accurately measure the variation of enthalpy of combustion (‘Q’) for different types of alcohols. This allows for a standard ground of comparison between the alcohols of different…

4.1 Strength of Anisotropy “The strength of anisotropy is calculated by the “kern and Richter” formula which gives the magnitude anisotropy k= (Vmax –V min)/Vmean, where Vmax and Vmin are maximum and minimum velocity. For P wave in the olivine crystal Vmax and Vmax are 9.89 and 7.72km/s respectively, so strength of anisotropy is 25%. For S wave k= 22% for Vmax and Vmin are 5.53 and 4.42 km/s respectively” [Seth stein 2003]. This anisotropy is the intrinsic anisotropy of the material defined as…

The FT-Raman and FT-IR spectroscopic analysis of 2'-nitroacetophenone (2NAP) were performed. The vibrational spectra of 2NAP was found by applying the Density Functional Theory Calculations based on Beck3-lee-yang-parr (B3LYP) level with the use of the standard 6-31G*/6-311+G** basis set. The vibrational wave number for the optimized geometry was calculated at the same level of theory. The computed values of frequencies are scaled using an appropriate scale factor to give up the excellent unity…
