heat
1. AB is a metal rod. It is being heated at end A.Finally, will the average kinetic energy of the atoms at end B be equal to that of the atoms at end A? Please explain.
2. 是否所有物質都有solid, liquid, gas 共三種states?請解釋。

xxxxxx1122: 題一，我也是認為答案是yes.因為heat is transfered from end A to end B by conduction.Though the atoms at end A will vibrate vigorously first, finally, the temp. at end B must be the same of that at end A.

但根據MODELLED ANS： temp. at end B< temp. at end A∴average KE of atoms at end B< that of atoms at end A 這怎解釋？
