P=$\frac{nRT}{V}$.
This allows a straight line to be drawn for the effect of $\frac{1}{V}$ on P.
For the sketched graph above, which components of the equation P=$\frac{nRT}{V}$,relate to the gradient and
y-intercept of the straight line?
A. Gradient is nRT;y-intercept is V
B. Gradient is nRT;y-intercept is 0
C. Gradient is $\frac{1}{V}$;y-intercept is P
D. Gradient is$\frac{nRT}{V}$;y-intercept is P
