Calories :: essays research papers

People argon, by nature, very gullible, nieve and border on ignorance. in that location 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 calorie. Millions of Americans read the labels of food containers and worry endlessly approximately the number of calories that a food contains. This is a classic example of tender-hearted ignorance. How can one worry about something and non know what it is, where it comes from, and what it does?A French scientist, Antoine Lavoisier coined the term calorie, actually caloric, in the eighteenth century. Mr. Lavoiser sight that chemical centerfield reactions gave off heat. He believed that this heat was some form of fluid, much analogous water, that carried the heat away from the reaction. (Rothman, 69) Antoine was on the right track he plainly got on the wrong train.Benjamin Thompson, also an eighteenth century scientist, observed that while drilling through brass with a dull geek he could produce enormous amounts of heat yet not bushel very deeply into the brass. This led Mr. Thompson to the conclusion that heat was the product of work, not the invisible fluid caloric.Joseph Black, yet another scientist of the seventeen atomic number 6s, discovered that it took various substances varying amounts of heat to raise one gram of a substance one degree Celsius. He called this specific heat. Mr. Black also spy that when mercury at fifty degrees is mixed with equal amounts of water at zero degrees the resulting mixture would be only one degree. From this, he cerebrate that heat and temperature were not the same. In order to give the scientific earth a standard of measure Mr. Black termed the amount of heat take 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 t o by the food and Drug Administration are actually kilocalories. That is one thousand times greater than those Mr. Black discovered. When Americans beat down to breakfast and eat a serving of Frosted Flakes, they are not ingesting one hundred sixty calories but one hundred sixty THOUSAND calories.
