How does a alcohol thermometer work
WebThermometers are made of materials that can measure and indicate temperature changes. Common thermometer materials include mercury, alcohol, and bi-metal strips. Mercury is used in most traditional thermometers, while alcohol is often found in clinical thermometers. Bi-metal strips are used in inexpensive digital thermometers. The material … WebPlace the protective cover on the tip of the thermometer. Gently insert the thermometer until the ear canal is fully sealed off. Press and hold down the button for 1-2 seconds until you hear a beep (follow the manufacturer’s instructions). Remove the thermometer, discard the cover, and record temperature and time.

WebWhen heat goes into the glass thermometer, the glass expands slightly (thermal expansion). This happens before enough heat is transmitted to the alcohol for it to start expanding (thermal conductivity). Thus, the height of the alcohol goes down slightly because the capillary of the thermometer is slightly larger. in-car cellular phoneWebJan 6, 2024 · As the name suggests, it can measure the temperature of any liquid and distinguish them on the basis of it.
