Review the behavior of the gas phase vs. the liquid phase. Solution: a) The volume of the liquid remains constant‚ but the volume of the gas increases to the volume of the larger container. b) The volume of the container holding the gas sample increases when heated‚ but the volume of the container holding the liquid sample remains essentially constant when heated. c) The volume of the liquid remains essentially constant‚ but the volume of the gas is reduced. The particles in a gas are further apart than

Gas Compressor Brief Introduction A gas compressor is a mechanical device that increases the pressure of a gas by reducing its volume. Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. As gases are compressible‚ the compressor also reduces the volume of a gas. Liquids are relatively incompressible‚ so the main action of a pump is to pressurize and transport liquids. Types of Compressors Centrifugal compressors Centrifugal

The gas in the natural world follows the specific laws. Different laws have their own explanations and they apply to the real things in this real world. Charles’s Law‚ Boyle’s Law‚ Combined Gas Law‚ Avogadro’s Law and Gay-Lussac Law explain the gas properties and show the scientists how the gas functions. Charles’s Law describes how gases tend to expand when the heat is added. When the temperature increases‚ the volume of the gas increases. During the winter season‚ a football inflates inside gradually
