Maxwell-Boltzmann Distribution and Thermal Contact
Two blocks at different initial temperatures are brought into thermal contact. The molecular kinetic energies in each block are described by the Maxwell-Boltzmann distribution. Which statement best describes the change in these distributions as the blocks approach thermal equilibrium?
A
The distribution becomes more narrow in both blocks
B
The distribution shifts to higher energies in both blocks
C
Only molecules with the highest energies participate in transfer
D
The distribution shifts toward lower energies in the hotter block
