WebAs the temperature around the thermometer's bulb heats up, the liquid rises in the glass tube. The glass tube is mounted on a backboard that is marked in units called degrees. When it is hot, the liquid inside the thermometer will expand and rise in the tube. The opposite happens when it is cold. WebAs the temperature of the object increase, it will emit more radiation, and the actual amount of radiation could be measured and correlated to its temperature. When a cold alcohol thermometer is placed in a hot liquid, the column of alcohol goes down slightly before going up. Explain why.
