Chemistry water displacement

WebThe method of collecting the gas depends on its density relative to air, unless you collect the gas over water in an inverted test tube - then it doesn't matter. If the gas is less dense than air e.g. hydrogen or ammonia, the test tube must be inverted and the gas will rise into it to displace the more dense air. WebNegative displacement, on the other hand, is a type of fluid displacement where the volume of the displaced fluid varies with the pressure and temperature changes. This type of displacement is often used in devices such as turbines and engines. Examples: Positive displacement is a reciprocating pump used to transfer water from one location to ...
