Detailed explanation-1: -When heated, the molecules of the liquid in the thermometer move faster, causing them to get a little further apart. This results in movement up the thermometer. When cooled, the molecules of the liquid in the thermometer move slower, causing them to get a little closer together.
Detailed explanation-2: -The expansion of mercury in the thermometer is due to the high temperature of the hot water. Thus, the reading of the thermometer tells the temperature of the hot water.
Detailed explanation-3: -If you are measuring something that is warm or hot, the liquid in the thermometer will expand and rise inside the thermometer’s glass tube. If you are measuring something cool or cold, the liquid will contract and move down the tube. Markings on the side of a thermometer help you measure the temperature.
Detailed explanation-4: -The metric system, including Celsius, is the official system of measurement for almost all countries in the world. Most scientific fields measure temperature using the Celsius scale. Zero degrees Celsius is the freezing point of water, and 100 degrees Celsius is the boiling point of water.
