Question

c) x 2 feet. 5. Which of the graphs of molecular displacement versus horizontal distance in Figure 3-16 cor corresponds to the pressure graph in Figure 3-15? d

is asking which of the graphs in figure 3-16 (molecular displacement vs horizontal distance graph) correspond or relate to figure 3-15 ( pressure graph) ?

Answer 1

Displacement will be maximum at high pressure and at low pressure. And displacement will be zero at normal pressure.

Here at 0.0 ft pressure is high hence displacement should be maximum.

At 1.0 ft pressure is normal hence displacement should be zero.

At 2.0ft pressure is low hence displacement should be maximum.

Hence option d is correct
