The pressure of a fixed amount of compressed nitrogen gas in a cylinder is given, in atmospheres, by

where T is the temperature of the gas, in Kelvin, and V is the volume of the cylinder, in liters. Figures 8.6 and 8.7 give cross sections of the function f.

(a) Which figure shows cross-sections of f with T fixed? What does the shape of the cross-sections tell you about the pressure?

(b) Which figure shows cross-sections of f with V fixed? What does the shape of the cross-sections tell you about the pressure?
