A eudiometer is a laboratory device that measures the change in volume of a gas mixture following a physical or chemical change.
A eudiometer is a laboratory device that measures the change in volume of a gas mixture following a physical or chemical change. The eudiometer is similar in structure to the meteorological barometer. Similarly, a eudiometer uses water to release gas into the eudiometer tube, converting the gas into a visible, measurable amount. A correct measurement of the pressure when performing these experiments is crucial for the calculations involved in the PV=nRT equation, because the pressure could change the density of the gas.
