Question

How do you graph pressure and volume?

Answer 1

if you talk about pressure and volume of a gaseous substance at constant temperature, you should use gas equation e.g.,PV = nRT

if n = constant , T = constant and R is already a constant term. e.g., Universal gas constant.

then, PV = constant.

this means P is inversely proportional to volume or V is inversely proportional to pressure.

know you know the graph of f(x) = 1/x is hyperbolic so, graph between P and V must be hyperbolic as shown in figure.
