Question

question 23 4 pts kinetic molecular theory predicts that pressure rises as the temperature of a gas increases because the gas molecules collide less energetically with the wall the average kinetic energy of the gas molecules decreases there are more frequent and more powerful collisions the gas molecules collide less frequently with the wall

Explanation:

1. Recall the Kinetic Molecular Theory: As temperature increases, gas molecules' average kinetic energy increases.
2. Analyze each option:

• Option 1: Incorrect. Higher temp means more energetic collisions, not less.
• Option 2: Incorrect. Higher temp increases average kinetic energy, not decreases.
• Option 3: Correct. Higher temp leads to faster, more energetic molecules, causing more frequent and powerful collisions with the container wall, increasing pressure.
• Option 4: Incorrect. Higher temp increases collision frequency, not decreases.

Answer:

C. there are more frequent and more powerful collisions
