Thermodynamic temperature

Tempkin isotherm contains a factor that explicitly takes into account adsorbing species-adsorbate interactions . This isotherm assumes that the heat of adsorption of all molecules in the layer decreases linearly with coverage due to adsorbate-adsorbate interaction and adsorption was characterized by a uniform distribution of binding energies, up to some maximum binding energy. Tempkin isotherm has generally been used in the linearized and rearranged form as following:…

Content Stoichiometry is the relationship of the masses of the reactants and products in a chemical reaction. For a given mass of a substance in a reaction, the mass of any other substance in the reaction can be obtained using the coefficients of the balanced chemical equations and the molar masses of the substances involved. The amounts obtainable from a balanced chemical equation are called stoichiometric amounts (Villamar Jr., 2004). As what was said in the introduction, the first topic that…

In this lab, a probe was connected to a MeasureNet device, in which it recorded the change in temperature as a function over time. The data for each part was then saved under separate files on an online data storage program that could be accessed later. The overall goal of the lab was to measure and calculate the change in enthalpy by using a calorimeter to measure temperature changes within the Styrofoam cup system. In parts 1 and 4, the goal was to measure the enthalpy change of acid-based…

Do not touch the side or bottom of the beaker with the thermometer, this will result in an inaccurate temperature reading. Record the starting temperature in the corresponding area of the data table. Leave the thermometer in the water. Carefully place a sprig of the Elodea plant into the beaker of water. Secure the gas pressure sensor to the second ring stand with a utility…

Basic concept of Qi Qi (氣), in Chinese, refers to all gaseous substances that make up the universe. Externally, it forms the air and gases in the atmosphere. Internally, Qi is regarded as the energy stored in human body. The concept of Qi can be traced back to the Ancient Chinese Philosophy, in which people held the belief that Qi is the fundamental life force of everything; it forms all matters in the universe and ranges from external environment to the internal energy stored inside the body.…

II. Energy balance model The methodology adopted has been used to predict the heating and cooling requirements of different buildings. Energy needs, expressed in Kilowatt-hour (kWh) are given commonly by equation 1: (01) In the heating season, equation 1 is simplified as follows: (02) In the cooling season, equation 1 is transformed into the following form: (03) During inter-seasons periods, if the heat generated by energy sources (lights, occupants and their activities) is higher than the…

Pure Copper Iodide were synthesised and the mass percentage of Copper in purified Copper (I) Iodide sample were determined by applying Beer’s Law in UV-Vis spectroscopy. Absorbance value of Cu-cuprizone solution was measured. Using the absorbance value of 0.3576 , the concentration of the Cu-cuprizone solution were obtained at 0.001389g/L with reference to the graph of the standard solution A to D. The graph of absorbance against concentration of the standard solution A to D shows a linear…

as Polydimethylsiloxane (PDMS) and Tetra ethoxy orthosilicate (TEOS) is synthesized. Transmittance of about 90-95 % is obtained in the visible region (400-700 nm) and the synthesized substrate show better thermal characteristics and withstands temperature upto 200 oC without any significant degradation. Characteristics such as transmittance (T), absorption (A), refractive index (n) and extinction coefficient (k) are also reported. Keywords: ); Flexible Polymer Substrate, Polydimethylsiloxane…

The above graph shows temperature of Sn0.3Ag0.7Cux In alloy as a function of indi-um weight percentage. Initially with no traces of Indium, the solidus temperature & liquidus temperature are 219.40̊C and 241.70̊C. It clearly shows that the temperature range goes wider as the concentration of indium is increased [6]. This is not a cost effective solution as indium is very costly. Titanium oxide nano particles addition led to temperature changing from 217 to 217.64 degree Celsius [7]. Zinc oxide…
