The thermometer revolutionized medicine, allowing for more accurate diagnosis and treatment of illnesses. It also played a crucial role in scientific advancements by enabling precise measurements for experiments and research. Additionally, it transformed industries by enhancing quality control in manufacturing processes.
Sensitivity of a thermometer is calculated by dividing the change in temperature measured by the thermometer by the change in the actual temperature. This gives a measure of how accurately the thermometer can detect small changes in temperature.
Temperature affects a thermometer by causing the liquid or material inside to expand or contract, leading to a change in volume. This change in volume is measured by the scale on the thermometer, so as temperature increases or decreases, the level of the liquid or material inside the thermometer will rise or fall accordingly.
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
The resolution of a digital thermometer is the smallest incremental change in temperature that the thermometer can detect and display. It is typically expressed in degrees Fahrenheit or Celsius. For example, a thermometer with a resolution of 0.1°C can display temperature changes as small as one-tenth of a degree.
Using materials with a higher coefficient of thermal expansion, such as certain metals like nickel, will provide greater sensitivity in a thermometer. These materials will change their dimensions more in response to temperature variations, resulting in a more noticeable change in the reading of the thermometer.

World's tallest thermometer was created in 1991.
Yes as your fingers are warmer than the air surrounding the thermometer bulb.
There should be a small cap, or hatch (maybe attached with a tiny screw) that exposes the battery compartment.
a towel will ,change your baby's temperature to cold
Yes,its called as "liquid crystal thermometer".

Physical. The mercury doesn't change.
physical change
No, the expansion of liquid in a thermometer is a physical change, not a chemical change. The liquid simply expands or contracts based on the temperature, without any change in its chemical makeup.
