Question

increasing ______ of collisions or ______ of collisions will cause pressure to increase. speed, duration intensity, volume magnitude, time forcefulness, frequency

Explanation:

In physics, pressure is related to the force and frequency of molecular - level collisions. When the forcefulness (which is related to the force of each collision) and frequency (number of collisions per unit time) of collisions increase, pressure increases.

Answer:

D. forcefulness, frequency
