Introduction The primary objective of this lab is to be able to determine the specific heat of a reaction by using a calorimeter. A calorimeter is a device used to determine the specific heat of chemical reaction or a physical change. The specific heat a reactions is used to refer to the amount of heat that is lost or gained when one gram of a particular substance increases or decreases by one degree Celsius. When a chemical reaction occurs in an open container most of the energy gained or lost

Ice-Fili (АЙС-θИЛИ) You cannot defeat a nation that enjoys ice cream at minus 40 Celsius. — Winston Churchill To survive in Russia’s ice cream industry during the 11 years since the collapse of the former Soviet Union was no small feat (see Exhibits 1 and 2). To be successful in these turbulent times was nothing short of amazing to industry observers. In 2002‚ Ice-Fili‚ a midsized Russian company with more than $25 million in sales‚ was Russia’s top ice cream producer. Surprisingly‚ it had

After six years of service he decided to further his expertise serving in a variety of other roles elsewhere in the frozen foods industry. He later retuned as CEO in 1988 and was inspirational in leading the company through the vast changes that ensued. Ice Fili are Russia’s top ice cream producer so one could forgive Shamanov

Ice man Have you ever been treated unfairly? Have you ever been treated like you have no rights at all? Most people have‚ but few of them have been treated as badly as Victor and his friends were in “Ice Man” written by Elmore Leonard‚ just because they are Native Americans. “Ice Man” is fiction. In “Ice Man” the narrator is an unknown 3rd person narrator. He does not enter the characters minds‚ he only tells us what they say and what they do. And therefore he must be a person that does not take

Fire and ice The world could possibly end in two ways. The author‚ if he had to perish twice would like to try both. Fire is desire and I think ice is equated to hate. I don’t think he necessarily thinks one has a greater destructive power than the other‚ but that his first choice would be fire/desire. This is because I think that the fire represents love. Both fire/desire and ice/hate can be extremes of emotions and the elements. Do you find it interesting that his last name is Frost?

She does not care if she hurts our feeling‚ she just cares about the goal-which is to win at competitions. She uses instrumental

The Webster’s Dictionary defines calorimeter as‚ “an apparatus for measuring quantities of absorbed or emitted heat or for determining specific heats.” While direct calorimeters measure the amount of heat produced in a small chamber‚ indirect calorimeters measure the amount of heat produced by taking into account the amount of consumption of oxygen and elimination of carbon dioxide. Both contain the same concept‚ but have a different approach. Indirect calorimetry is the preferable way for physiologists
