Physics · Thermodynamics
Van der Waals' equation for a real gas may be written as: (Where a, b, and R are the characteristic constants of a particular gas, 'p' is the absolute pressure, 'v' represents the volume per unit mass, and T is absolute temperature).
- 1(p - a/v2)(v + b) = RT
- 2(p - a/v)(v2 + b) = RT
- 3(p + a/v)(v2 - b) = RT
- 4(p + a/v2)(v - b) = RT✓
Correct answer
(p + a/v2)(v - b) = RT
