Calories :: essays research papers

People atomic number 18, by nature, very gullible, nieve and border on ignorance. There are very few that strive for understanding. Most accept what is told them by friends, the media and the government without question. Take for, instance, the small calorie. Millions of Americans read the labels of food containers and worry endlessly about the number of calories that a food contains. This is a classic example of human ignorance. How can one worry about something and not know what it is, where it comes from, and what it does?A French scientist, Antoine Lavoisier coined the term calorie, genuinely caloric, in the eighteenth century. Mr. Lavoiser observed that chemical reactions gave off heat. He believed that this heat was some form of fluid, much like water, that carried the heat away from the reaction. (Rothman, 69) Antoine was on the remedy track he merely got on the wrong train.Benjamin Thompson, also an eighteenth century scientist, observed that while drilling through brass with a dull bit he could produce enormous amounts of heat yet not get very deeply into the brass. This led Mr. Thompson to the conclusion that heat was the output of work, not the invisible fluid caloric.Joseph Black, yet another scientist of the seventeen hundreds, discovered that it took different nucleuss varying amounts of heat to raise one gram of a substance one degree Celsius. He called this specific heat. Mr. Black also noticed that when mercury at fifty degrees is mixed with equal amounts of water at vigour degrees the resulting mixture would be only one degree. From this, he concluded that heat and temperature were not the same. In order to give the scientific world a modular of measure Mr. Black termed the amount of heat required to raise the temperature of one gram of water one degree Celsius a calorie.The problem encountered here is that the calorie on food containers is not quite the same as Mr. Blacks. The calories referred to by the food and Drug Administration are actually kilocalories. That is one thousand multiplication greater than those Mr. Black discovered. When Americans sit down to breakfast and eat a serving of Frosted Flakes, they are not ingesting one hundred sixty calories however one hundred sixty THOUSAND calories.
