formed as the granules melt and wet the pipe surface. Electric current is passed along the pipe for preheating (Bird, Stewart, & Lightfoot, 2002). The situation under study is about the electrical heating of a pipe with the assumptions that over a temperature range, electrical conductivity, ke (ohm-1cm-1), is constant, and that the local rate of electrical heat production, Se (E/cm3), is uniform throughout the pipe wall. Heat losses through the pipe are assumed…

the sunshine hours, from 10:00 AM to 06:00 PM IST. Both the collectors were inclined at an angle of 13$degree$, facing south side according to the geographic location of Madurai. The inlet and outlet air temperature, ambient temperature, top and bottom of collector surface temperatures were measured at different state points using K-type thermocouples. The data were recorded for every 15 minutes by 34972A Agilent data logger and stored…

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…

Part A It was important to test each of the four samples given for the largest increase in temperature. To begin, 20ml of purified water was poured into a beaker. Its temperature was then recorded in real time as 1.5g of the chosen salt was added. The computer monitored the process and returned the maximum observed temperature. The total change on temperature was compiled into a table similar to that of table 1. It was essential to repeat the process with each salt, taking…

position statement was created it has helped some athletes, athletic trainers, allied health care providers, and their coaches with educating them on how dangerous heat illnesses is. Heat illness comes from physical activity with the rising of temperature and humidity. Most athletes training or playing summer experience this illness. Heat illness can restrict athletes from playing in their sports. It is not likely for any winter athletes to get the illness. Sports like football, soccer, and…

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…

freezing points of pure solvent and solutions using cooling curves. Calculate the freezing point depression for the solutions of unknown. Calculate Molar Mass of unknown solute. Introduction: When a solute is dissolved in a solvent, the freezing temperature is lowered in proportion to the number of moles of solute added. This property, known as freezing-point depression, is a colligative property; that is, it depends on the ratio of solute and solvent particles, not on the nature of the…

Introduction: Alcohols are used in everyday life and as a result they are of great interest to chemists, specifically in regards to energy output. Energy output is extremely important when it comes to classifying a compound’s uses. For example, a compound with an explosive energy output can be implemented as a fuel for cars or other vehicles. This is the very reason that accurate information about the heat and/or energy output of alcohols are in high demand in many industries. Fuels release…

ensure offspring will be viable and competitive members of a population. One of the basic features of reproductive success is providing offspring an environment with the necessary features for effective development, such as nutrients and water, temperature control and protection from predators. Oviparity and viviparity are two methods that provide developing embryos with the environment they require to successfully develop. Oviparity can be defined as a reproductive mode where a portion of…

Ctenophora, what role does temperature and rainfall play in their movements? To get a better understanding of how population densities change with weather, samples were taken during different periods of precipitation and temperature; rain the day before, clear the day before, warm temperatures, and cool temperatures. In the end, there were minor differences between the densities of Ctenophora per 3.5 liters, but not significant enough to make a conclusion of temperature and rainfall directly…
