Adiabatic free expansion of a gas For an adiabatic free expansion of an ideal gas, the gas is contained in an insulated container and then allowed to expand in a vacuum. Source: Internet

Although pressure is defined mechanically, a pressure-measuring device, called a barometer may also be constructed from a sample of an ideal gas held at a constant temperature. Source: Internet

An idealized thermometer is a sample of an ideal gas at constant pressure. Source: Internet

But, already before the establishment of the ideal gas law, an associate of Boyle's named Denis Papin built in 1679 a bone digester, which is a closed vessel with a tightly fitting lid that confines steam until a high pressure is generated. Source: Internet

For an ideal gas the internal energy is given by : where is the number of degrees of freedom divided by two, is the universal gas constant and is the number of moles in the system (a constant). Source: Internet

For an ideal gas, the temperature remains constant because the internal energy only depends on temperature in that case. Source: Internet
