A thermometer works when a device that measures temperature.
This liquid is sometimes colored alcohol but can also be a metallic liquid called mercury.Both mercury and alcohol grow bigger when heated and smaller when cooler.Inside the glass tube of a thermometer,the liquid has no place to go but up when the temperature is hot and down when the temperature is cold.
A common thermometer uses mercury in a glass tube.An increase in temperature makes the mercury expand and rise in the glass tube.
One type of thermometer is a narrow containing mercury or alcohol which extends along the tube as it expands.
The outside of the thermometer has a scale on it witch tells you what temperature the liquid has detected.
Another type is a digital thermometer,which uses electronics to measure the temperature.
