Question Description

I uploaded a finished lab report and tables with my numbers, follow the same format in the lab report and use the numbers that i provided. also, don't use the same words in the lab report. just use it to help you get the idea and understand how to do it.

thank you.

The objective of the experiment is to measure the pressure and the volume due to
the effect of the temperature for carbon dioxide (CO2) a pure component. With a PVT
simulator, the Peng-Robinson equation is used to calculate the phase behaviour
(Robinson, et al. 1985). The value of the pressure is read when the valve is open. The
students determined the relationship between the volume and pressure by injecting or
withdrawing mercury. The bubble point appears when the volume of Carbon dioxide
in the Gas phase is 0.002cc. The due point appeared when the volume of carbon
dioxide in the liquid phase is 0.002 cc (Robinson, et al. 1985).
In the experiment we are to find the dew and bubble point for the same
component in three different temperatures to show temperature effects on the due and
bubble point, the data collected in an excel sheet. The role of the mercury is to
displace fluids and does not react with carbon dioxide.
The simulator is in use because the mercury could be toxic. Pressure increased
inside the cell the more the mercury injected. The liquid and the gas were displayed as
brown and yellow respectively. The pressure-volume of CO2 calculated at
temperature of 85oF was 946.08psi and 13.712. The data collected in excel sheet was
used to make a line chart that displays the relationship between the pressure and the
total volume in each experiment.

Theory, concepts and objective of the experiment
Molecules of pure components in the gas phase get closer and convert to liquid
with increase in pressure (Heydemann,1963). With decre...
