4. When the temperature rises, what happens to the peak of the curve in the Maxwell-Boltzmann distribution graph? a) Shifts forward and upward b) Shifts forward and downward c) Shifts backward and upward d) Shifts backward and downward
Answer: b Explanation: The peak moves ahead but downward as the temperature rises. This is because when temperature rises, the most probable kinetic energy rises, while the percentage of molecules with most probable kinetic energy drops.
