温度计的发明给我们日常生活和工农业生产带来了莫大的便利,同学们一定很好奇:温度计是怎么发明的?依据的是什么原理?目前有哪些种类?一、温度计的发明1593年,意大利物理学家伽利略依据气体热胀冷缩的原理研制出了世界上首支温度计.如图1所示,将一根长约45 cm、麦秸秆粗细的玻璃管,一端吹成鸡蛋大小的玻璃泡,另一端开口,先给玻璃泡加热,再把开口的一端倒插入盛有有色水的玻璃容器内,使水沿管 The invention of the thermometer has brought great convenience to our daily life and the industrial and agricultural production. The students must be very curious: how the thermometer was invented? What principle is based on? What are the current types? 1. The invention of the thermometer In 1593, Italy Galileo, the physicist, developed the world’s first thermometer based on the principle of gas expansion and contraction, as shown in Figure 1. A glass tube about 45 cm in length and straw thickness was blown into an egg-sized glass bulb , The other end of the opening, the first glass bulb heating, and then open the end of pouring into a glass container containing colored water, the water along the tube
