# Sketch the graph of pV vs p when the temperature of the gas is constant. here p means pressure and V means volume - showing you the direct relationship b/w p and V (by using pV). how to sketch it???

##### 1 Answer

We know that the Ideal gas equation is

where

Since temperature is kept constant the RHS of the equation is a constant.

As such the graph of

We can test this by plotting

The computer gives the equation for the best fit line as

This implies that the line starts at

Using only two significant figures for the

Therefore, within the limits of experimental error,
