Unformatted text preview: τ) ) where τ is the time constant Behaviour The objective of the pressure section of our lab was to discover the relationship between vapour pressure and temperature. We had a vessel filled up with warm water; we turned the heat on and the transducer, and started recording our data when the vessel reached 100 C and then following an additional 10 C from the previous recording. Until we ⁰ ⁰ have a sufficient amount of data. To find the relationship between temperature and pressure by using the ideal gas law: P1V1=N1RT1 P2V2=N2RT2 In this experiment, we have to assume that the concentration and the volume remain constant throughout the whole experiment. N1=N2 V1=V2 Therefore: P1/T1=P2/T2 We also have to look at the relationship between the absolute pressures of both gauges vs. the pressure transducer. We saw a linear relationship when observing the gauges vs. the pressure transducer. (Maybe you can add a sentence because I don’t know what kind of relationship this is) Words:250...
