一、概念规律 (一)三个状态参量 1、温度温度是表示物体冷热程度的物理量.是物体内分子热运动的平均动能的标志.温度数值的表示方法叫温标,常用的温标有摄氏温标和热力学温标两种. 2、体积气体的体积指气体占据的空间.由于气体容易扩散,能充满整个容器,其体积等于所在容器的容积.从微观讲,气体体积等于分子体积与分子间空隙之和.在国际单位制中,体积的单位是米~3、分米~3、厘米~3
First, the concept of law (a) three state parameters 1, the temperature is a physical quantity that represents the degree of cold and heat of the object. It is the sign of the average kinetic energy of the thermal movement of the molecules within the object. The representation of the temperature value is called the temperature scale, and the commonly used temperature scale is the Celsius temperature scale. And thermodynamic temperature standard two. 2, volume gas volume refers to the space occupied by gas. Because the gas is easy to diffuse, it can fill the entire container, its volume is equal to the volume of the container. Microscopically, the gas volume is equal to the molecular volume and the intermolecular gap And. In the International System of Units, the unit of volume is m~3, decimeter~3, cm~3
