The pressure 'p' of an ideal gas and its mean kinetic energy E per unit volume are related by the relation
- A. p = (4/3)E
- B. p = (3E)/2
- C. p = E/3
- D. p = (2E)/3
Answer: D. p = (2E)/3
Explanation: The average kinetic energy (E) per unit volume of an ideal gas is theoretically given by E = (3/2) * p, where p is the pressure. Rearranging this relationship to solve for pressure yields p = (2/3) * E.
