D)an increase in pressure requires a decrease in both density and temperature

Quizplus · Accepted Answer

According to the equation of state p = ρRT, an increase in pressure can be achieved by increasing density, temperature or both. This is because there is a direct relationship between pressure and density and temperature, as seen in the equation. However, it is not necessary for both to increase; only one or the other can increase to cause an increase in pressure. Therefore, choice A is the best answer.
