Various coefficients are used to represent the non–ideal behavior of real gases. A common one is called the second virial coefficient and has the symbol B. B varies with temperature, and at the temperature where B is zero, the gas acts almost exactly like an ideal gas. Graph B versus temperature for a gas.

What is the equation of the line that best fits the data?
Question 14 options:
|
|
B = (–2.0 × 10–7) T3 + (–0.0005) T2 + (0.0001) T – 10 |
|
|
B = (1.0 × 10–7) T3 + (0.0001) T2 + (–0.0005) T + 5 |
|
|
B = (–3.0 × 10–7) T3 + (0.0004) T2 + (0.0002) T – 20 |
