WebbIt's a thin straw-shaped piece of glass with a bulb at the bottom. The mercury pools in the bulb, but when it heats up, it expands. Because it can't expand through the bottom of the bulb, it is forced up the tube. That expansion, caused by the atoms flying around faster and taking up more space, is what makes the thermometer work. Webb16 nov. 2024 · In a mercury thermometer, the level of mercury rises when its bulb comes in contact with a hot object because mercury expands when the temperature is increased …

A thermistor measures the change in electrical current as a result of heat added or removed.

WebbUnlike mercury thermometers, which require you to wait for the mercury to heat before gradually rising to display the temperature, digital thermometers provide quick results. Temperatures of boiling are also controlled by mercury thermometers. How does a digital thermometer function without mercury?

WebbWhen the tip of the mercury thermometer touches the material it is measuring, the material conducts heat energy to the mercury. Then the mercury expands as it turns into a liquid and begins to rise up the tube. The place where the mercury stops on the scale is where you can take the reading of the temperature.
