温度计是测量温度的仪器 ,测量温度是通过观察随着温度变化的某种客观物理量来实现的。所选取的物理量可以是各种各样的 ,如固体的线度、液体的饱和气压、半导体的电阻率、被测对象的热辐射。中学物理教学中常用的温度计是玻璃液体温度计 ,它利用液体(测温工质 )的体膨胀测量温 Thermometers are instruments that measure temperature by measuring some objective physical quantity that varies with temperature. The selected physical quantities can be varied, such as the solid linearity, the saturation pressure of the liquid, the resistivity of the semiconductor, the thermal radiation of the object under test. High school physics teaching thermometer is commonly used in glass liquid thermometer, which uses liquid (temperature working fluid) body expansion measurement temperature
