题目

英语翻译
温度不同的物体混合之后,热量由高温物体传给低温物体,若装置和外界没有热交换,则系统最后将达到均匀稳定的平衡温度.其中高温物体放出的热量完全被低温物体吸收.此称为热平衡原理.
如图2-1,一绝热装置中放有一烧红的铁块和一常温金属球.将绝热板移走,使烧红的铁块与另一铁球接触,一段时间后发现铁块的红色渐渐退去,铁球颜色加深.

答案

After objects of different temperature are mixed,the object of higher temperature will conduct the heat to the one of lower temperature.If there is no heat exchange between the objects and others,the mixture will finally reach a steady temperature.The heat released by the object of higher temperature will completely be absorbed by the one of lower temperature,which is called the heat balance principle.
Take picture2-1 for example,a piece of red-hot iron and a metal ball of normal temperature are placed in an insulated container.Then with the insulation board removed,mix the red-hot iron and the metal ball,and after a while,you will find the colour of the red-hot iron will fade away while the colour of the metal ball will become deeper.
