Gas Laws Experiment - Lab Report Example

Conditions meant ideal conditions for gas to exhibit ideal behaviour include high temperatures and low pressures. Once experiencing these conditions, gas molecules seem to move independently without any possible collisions usually brought by interactions with other molecules.

The equation derived from these assumptions and relationship includes, PV = nRTR in this case represents universal gas constant whose value = 0.082056 L-atm/mol- Other equations obtained from both manipulation and rearrangements of the former equation include, Equation of state = PV/RTCombined gas law equation, PiVi/is = PfVf/TfIdeal gas Density and molar mass nR = PfVf/TfThis becomes, D/MM = P/RTMM = DRT/P = MRT/PVProcedure In doing this experiment, it entailed two sections, which were 1) Combined gas law and 2) Molar mass of condensed vapour.

Section 1Combined gas law Trough was filled with adequate water and its temperature was 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 its neck and clamped at that position. After about 10 minutes its temperature was taken and recorded as (Ti). The room’s ambient pressure was also taken using a barometer, which is also the same as that in a 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) – Water vapour pressure Tf. Then the remaining equation meant to obtain the final Vf was obtained using the relationship Vf = Vi {Pi / Pf}{Tf / Ti }.
