Phy一問：有關Heat

錯喇。
heat is the energy transfer due to temperature difference.
An object has more average kinetic when it is hot than it is cold.

completely wrong!!

It should change into An object has more kinetic energy when it is hot than it is cold.

because when an object has more kinetic energy, thevibration of the particles of the object will be higher.

So the temperature of the object will be higher.
