When the temperature of a fixed amount of an ideal gas is increased at constant volume, which of the following best describes how its Maxwell–Boltzmann distribution of molecular speeds changes?
(a) The most probable speed decreases, and the distribution becomes broader and lower.
(b) The most probable speed increases, and the distribution becomes narrower and higher.
(c) The most probable speed increases, and the distribution becomes broader and lower.
(d) The most probable speed remains unchanged, while the distribution becomes broader and lower.
