Question

In the following problem state the variables or combination of variables which should be plotted to check the suggested variation and state how the unknown may be found (thourgh the Slope and/or the intercept of the best fitting straight line y=mx+b. Because you are not given any numerical data it is just required to qualitatively describe your method of solution in few lines with schematic graphs.

The gas law for an ideal gas is PV=RT, P and T are measured variables, V is fixed and known. Determine R

Explanation / Answer

in this equation y=mx+b ... x and y are the variables and we can find the the unkno"wn m"by using slope and intercep"t b "of the ploted graph of the above said eqation.

plot the graph by taking "P" is along the y axis

                                and T is along the x axis

then slope the graph becomes the R ( if V is constant)
