Gas Laws - Lab Report Example Trough was filled with adequate water and its temperature elevated by three inches and meant to be uniform in all parts before inserting a 250 ml having a single-hole stopper. The inserted flask was put in the water bath in such a case the level of the water reached to its neck and clamped at that position. After about 10 minutes its temperature was taken and recorded as (Ti). Roomââ¬â¢s ambient pressure was also taken using barometer, which also the same with that in flask and recorded as (Pi). To determine Tf, the flask was inverted in a water bath for about 10 minutes whereby Vi then Vf were calculated and tabulated as necessitated. Then Pf was obtained using this relation, Pf = Pressure in the laboratory (Pi) ââ¬â Water vapour pressure Tf. Then the remaining equation meant to obtain final Vf was obtained using the relationship Vf = Vi {Pi / Pf}{Tf / Ti }. A 125 ml flask was covered with an aluminium foil at the top before a pin hole made to allow easy escape of volatile vapour put in the flask. The flask while inserted in the water bath it was heated to the temperature of T. Then the flask was taken out to cool before its contents measured and recorded as m. The volume V of the flask was also measured by filling it with
