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.
Continue ReadingSolving 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 >Robert Boyle discovered and used "Boyle's Law" to explain that when a volume of gas is decreased, pressure increases in the same proportion. Using this observation, Boyle helped create the modern definition of an element. He also developed a test that aided in the differentiation of acids from bases.
Full Answer >The unit of measurement for volume of natural gas is cubic feet, and the unit of measurement for the energy content of natural gas is a British Thermal Unit, or BTU. The term therm applies to 100 cubic feet of natural gas, and 1,000 cubic feet is an mcf.
Full Answer >In scientific terms, volume is three-dimensional space occupied by a gas, liquid or solid. Scientists measure volume in cubic units, such as liters, cubic meters, gallons and ounces. The most common equation to find volume is mass divided by density.
