low T high T speed → N

As temperature increases, the Maxwell-Boltzmann distribution

  • A

    Stays the same

  • B

    Becomes narrower with a lower peak at higher speed

  • C

    Becomes broader and the peak shifts to higher speeds

  • D

    Both A and C — broader, peak at higher speed, lower height

Explanation

At higher T, distribution flattens out (more spread), peaks at higher speed, and the average KE grows.
