Answer 2

Question:

a. a direct linear relationship

b. an inverse linear relationship

c. a direct nonlinear relationship

d. an inverse nonlinear relationship

Answer:

The correct option is;

d. An inverse nonlinear relationship

Step-by-step explanation:

From the universal gas equation, we have;

P·V = n·R·T

Where we have the temperature, T and the number of moles, n constant, therefore, we have

P×V = Constant, because, R, the universal gas constant is also constant, hence;

P×V = C

`P = (C)/(V)`

Since P varies with V then the graphical relationship will be an inverse nonlinear as we have

V P C

1 5 5

2 2.5 5

3 1.67 5

4 1.25 5

5 1 5

6 0.83 5

7 0.7 5

8 0.63 5

9 0.56 5

10 0.5 5

Where:

V = Volume

P = Pressure

C = Constant = 5

P = C/V

The graph is attached.
