At constant volume, temperature is increased, then:

Question

G1 Physics · Accepted Answer

Step 1: Increasing absolute temperature increases molecular RMS speed because vRMS ∝ √T. Step 2: At fixed container volume and fixed gas amount, number density n remains constant. Step 3: Collision rate per molecule and collision frequency on container walls increase with typical molecular speed. Step 4: Thus the number of collisions per unit time increases. Final answer: (B).
