Robert Boyle's air pump. In the history of science, pneumatic chemistry is an area of scientific research of the seventeenth, eighteenth, and early nineteenth centuries. . Important goals of this work were the understanding of the physical properties of gases and how they relate to chemical reactions and, ultimately, the composition of

In pneumatics, the working fluid is air or another gas which transfers force between pneumatic components such as compressors, vacuum pumps, pneumatic cylinders, and pneumatic motors. In pneumatic systems, the working gas also stores energy because it is compressible. (Gases also heat up as they are compressed and cool as they expand.
Pneumatics (from Greek πνεῦμα pneuma 'wind, breath') is the use of gas or pressurized air in mechanical systems. Pneumatic systems used in industry are commonly powered by compressed air or compressed inert gases. A centrally located and electrically-powered compressor powers cylinders, air motors, pneumatic actuators, and other ...
An air-operated valve, also known as a pneumatic valve, is a type of power-operated pipe valve that uses air pressure to perform a function similar to a solenoid. As air pressure is increased, the compressed air starts to push against the piston or diaphragm walls which causes the valve to actuate. Whether the valve opens or closes depends on ...
In general, based on the application, a pneumatic cylinder is usually a single-acting cylinder, where there is a single port in the cylinder. In single-acting cylinders, the port extends using compressed air and retracts using an open coiled spring. In double-acting cylinders, two ports both extend and retract using compressed air.
Four items are required for gas collection with a pneumatic trough: [2] The trough itself, which is a large glass dish or a similar container. A gas bottle (or bulb), to hold the gas collected. A way to support the gas bottle or bulb, such as a beehive shelf or a hanger (as with Stephen Hales' design). A liquid in the trough.
where P is the pressure of the gas, V is the volume of the gas, and k is a constant for a particular temperature and amount of gas.. Boyle's law states that when the temperature of a given mass of confined gas is constant, the product of its pressure and volume is also constant.
