物理問題一問詳細解釋...唔要老吹(關於熱既問題)

熱係粒子震動而產生,震動愈強烈,就愈多熱.
物質會傳熱是當一個粒子同另一個粒子接觸時,震動影響另一個粒子也隨著震動,一個接著一個,直到兩個物件的震幅一樣~
咁佢地既溫度就一樣~

任何粒子都可以傳導~
金屬粒子有多些電子,所以會傳熱得快d.

傳熱仲有對流同輻射可以傳到熱~
以上資料由我自己打出,不得复制!!!!

"All materials" can conduct heat. It is only that some materials conduct heat at a faster rate than others. Those that conduct heat fast are termed as good (thermal) conductors, whereas those that conduct heat slow are termed as bad conductors, or insulators.<====GOOD ANS.

點解有些物質會傳熱??

All materials can conduct heat. It is only that some materials conduct heat at a faster rate than others. Those that conduct heat fast are termed as good (thermal) conductors, whereas those that conduct heat slow are termed as bad conductors, or insulators.
符合什麼條件的質才會傳熱??
Heat conduction in a substance is attributed by the presence of free electrons. Heat causes more vigorous vibration of these free electrons, and the vigorous vibrations are conveyed by the free electrons through collisions from one end of the substance to the other, thus transferring heat.
Since metals are normally have more free electrons than non-metals, metals are therefore good conductors of heat. Non-metals, generally possess much less free electrons, are bad conductor of heat.
From the above description, it is not difficult to understand why good thermal conductos are usually good electrical conductors.
