Here’s something we tend to take for granted: drop a few ice cubes into a glass of water at room temperature, and in a few minutes the water will cool.
这是我们习以为常的事情:在室温状态下将冰块放入水中,几分钟后水会变凉PVtxD0YH07
How does this work?
这是什么原理呢?
Heat is a measure of molecular activity: the faster a thing’s molecules move, the more heat that substance contains.
热量是分子活动的指标:分子移动的速度越快,物体所含的热量越多@Tjw5.1t=v~0u@=]u

And because everything is made of molecules, and molecules are in constant motion, everything contains at least some heat.
由于所有物质都是由分子组成,而分子一直在活动,因此每个物体或多或少都包含一些热量9^]J(,wM#(,0GD^HH
As we know, ice is colder than room temperature water.
众所周知,冰的温度低于室温状态下的水%Bw@3O)L+eid]kU[m
Because ice molecules move slowly and cluster tightly together, they produce a relatively low amount of heat.
由于冰分子移动缓慢且聚集得十分紧密,因此它们产生的热量相对较少aob^.!76y=B
When ice is placed in a glass of water whose molecules are moving at a greater rate, the ice begins to absorb energy,
如果将冰块放入一杯分子移动较快的水中,冰块会开始吸收热量,
because heat always travels from regions of relative warmth to colder areas in order to equalize temperatures.
为了使温度均衡,热量会从高温处向低温处转移UTaX2Tf0SD%JC@O
