Question

The data in the table below represents the pressure of the gas as the temperature changes. Plot a graph of this data, using the blank graph provided below. Draw a trend line and calculate its slope. How are the variables related? What will the pressure of the gas be at 0°C?

What experiment is this?

Answer 9

can i send you the doc

i don't think it's an experiment

Answer 10

Well no need to. Have you tried plotting the data?

Answer 11

they show a graph

Answer 12

Might be a good idea to show the document (pdf please) or you use the draw tool. Give me all the information you got.

Basically what it sounds like to me is a P vs T graph for a gas in a closed container. To which we can approximate with the ideal gas equation:
\[\Large pV=nRT \rightarrow p=\frac{ nR }{ V } \times T\]
Assuming that you get a somewhat linear graph we can use the ideal gas equation for fitting as the ideal gas takes the linear form above with the slope:
\[\Large \frac{ dp }{ dT }=\frac{ nR }{V }\]
That is the theory part for it.

So by taking the data and putting into a graph we could get something like this yes:

Doing a linear fit we could get
