在人类的生产活动中,温度这个概念是十分常见的,它表征物质受热程度的数值。也可以说,温度是物体热力状态的一个参数;它表示物体内部分子直线运动的平均动能。假如有两个物体,甲物体的温度比乙物体高,也就是甲物体内部分子直线运动的平均动能比乙物体大。
The concept of temperature is very common in human production activities, and it is a numerical measure of the degree of heating of a substance. It can also be said that the temperature is a parameter of the thermal state of the object; it represents the average kinetic energy of the linear motion of the molecules inside the object. If there are two objects, the temperature of object A is higher than that of object B, that is, the average kinetic energy of linear motion of object A is larger than that of object B.
