Temperature

1. Fill a mason jar half-full with tepid water. Put it on the hotplate and raise the temperature to 98 degrees. Make sure you can keep it at this temperature for several hours. 2. Wash your hands. Cover the surfaces adjacent to your kitchen stove with paper towels. Place the test tube racks close to the stove on the paper towels. 3. Fill the pot with water and bring to a boil. Uncap your test tubes. Using your kitchen tongs, carefully drop your graduated cylinder, test tubes and their caps in…

The purpose of this experiment was to determine the thermodynamic properties of the entropy, enthalpy and free energy, as well as the solubility product of borax as a function of temperature from the dissolution of borax in an aqueous solution. Thermodynamics is the study of heat and its transformations. The properties of thermodynamics are entropy, enthalpy and free energy. The properties of thermodynamics can be viewed in terms of spontaneity. Spontaneity is a spontaneous change of a system…

or when you are away from your home on vacation, leave the cabinet doors to the under sink area open. This will help circulate the warm air in the space, keeping the pipes warm. You should also leave your heat on instead of turning it off. The temperature in your home may not drop below freezing, but it could fall dangerously low in the walls and crawl spaces. On particularly cold days, leave your faucets on so that they slightly drip water from them. This causes the water in the pipes to move,…

In this short story, by Jack London, a man is faced with the harshness of nature while attempting to travel through the wilderness in alarming cold temperatures. While the man seems quite at peace with the sever temperature, he becomes frantic as the story progresses. Throughout this journey, the man's only companion is his dog. As one reads through the story, it is inevitable to see the difference between the man and dog; therefor, it is simple to understand why the man dies and the dog lives.…

systems conducted, the Marcet boiler and Boyle’s law. The aim of this lab is to investigate in pressure-temperature relationship, Boyle’s law, as well as steam quality. The results of this experiment support both relationship, as well as successfully providing a value for steam quality. For the Marcet boiler experiment, it was found that the higher the system pressure, the higher the saturated temperature. For the Boyle’s law experiment, it was found that pressure is directly proportional to…

This will heat the metal to the temperature of the boiling water (100.0°C). 4. While the metal is heating, nest one Styrofoam cup inside the other. This will be your calorimeter. Since Styrofoam is a good insulator, 2 Styrofoam cups make an excellent calorimeter. 5. Measure the mass of this calorimeter with your scale. After you do this, fill the calorimeter about three-quarters…

1 Cure characteristics of CIIR with accelerated sulphur The cure characteristics of CIIR with an efficient type of accelerated sulphur (EV) system at different vulcanization temperatures are depicted in Figure 2 and Table 2 respectively. The EV system used here particularly to reduce the set properties at elevated temperature as it possesses relatively less polysulfidic linkages as compared to the conventional sulphur vulcanization (CV) system. It can be seen from the figure that the…

Ice transforms at a point of degrees. This degree would be 32 degrees Fahrenheit or 0 degrees Celsius. It must be at this degree or lower to transform into ice. If it is higher than the freezing point of water, then it will be a form of water or ice melting into water. The different molecules, or also called the things that make up the ice or water, are more dense in cold water. They become dense and come to each other which makes them tight into an ice cube. When the ice gets warm, it moves the…

determine the effect of temperature the mass specific metabolic rate (MR_MS) through oxygen consumption, if their body weight had an effect on mass specific metabolic rate and if the size/mass of the female swiss mice affected their response to the temperature. The different mice were placed within a plastic chamber and then placed in different variations of temperature of water (10°C, 15°C, 20°C, 25°C, 30°C). The procedure involved acclimating the mice up to the different temperature of ten…

teammates wore underneath their pads were always drenched with sweat after games and practices. Plank thought “there has to be something better,” and started designing a new athletic T-shirt that would stay light during exercise, even at the hottest temperatures. After some feedback and redesigning, Plank had a T-shirt made from microfibers that pulled moisture away from the body and kept athletes cool and dry. Plank made his first team sale to Georgia Tech at the end of 1996 and, after selling…
