According to Charles' Law, if you hold a gas at a constant pressure, the volume varies in direct proportion with the temperature in Kelvins. As volume goes up, so does the temperature; as temperature goes up, so does the volume. The general formula is V = cT, where V is volume, T is temperature and c is the constant particular to the gas in question.
Know MoreSolving direct proportion equations involves the use of a simple calculation with the terms involved. For example, if you have 2 liters of helium gas sitting at 400 K, and you increase the temperature to 800 K, finding the new volume is fairly simple. If V = cT, in this instance you have 2 = 400c, making c 1/200, or 0.05. Finding the new volume would require this equation: V = 0.05T. With a temperature that is now 800k, you solve: V = (0.05)(800). The new volume is 4 L. This matches the idea of direct proportion because the temperature doubled, and so did the volume.
One of the most commonly used experiments that teachers use to demonstrate Charles' Law involves immersing a cylinder that contains a gas under a piston into a heat bath. As the heat increases, the gas pushes the piston upward, increasing the volume.

Full Answer >There are approximately 2.1 pints in a U.K. liter. A liter is a measurement for liquid ingredients in the metric system, which is used by the United Kingdom while pints are used for measurement in the U.S. system.
Full Answer >One cubic foot of volume contains 29.92 fluid quarts or 25.71 dry quarts. Conversely, one fluid quart consists of 0.033 cubic feet of volume and one dry quart comprises 0.039 cubic feet.
Full Answer >The U.S. Department of Transportation states the maximum width for commercial motor vehicles is 102.36 inches, with a length of anywhere from 48 to 53 feet and a height of 13 to 14 feet. There is no legal height limit for the federal government, but the individual states set heights at which trailers can travel.
