What else can I help you with?
Why does the height of the liquid of a thermometer increaseswhen the temperature goes up?
Thermal expansion of the fluid inside the thermometer.
What happens to the thermometer when the temperature goes up?
When the temperature goes up, the mercury or alcohol inside the thermometer expands, causing the level to rise. This increase in volume is directly correlated with the increase in temperature, allowing the thermometer to indicate the higher temperature.
What happed to the particles inside of a thermometer when the temperature goes down?
When the temperature goes down, the particles inside a thermometer lose kinetic energy and move slower. This causes them to contract and move closer together, leading to a decrease in volume. This change in volume is what allows the thermometer to measure lower temperatures.
Why the alcohol level in a thermometer goes down when it's cold?
When the temperature drops, the alcohol in the thermometer contracts and takes up less space. This results in the alcohol level appearing to go down in the thermometer.
What is a thermometer bore?
A bore refers to the extremely fine or narrow tube found in a thermometer. It is called a narrow bore or a capillary.
Who invented the maximum-minimum thermometer?
JAMES SIX invented the Maximum and Minimum thermometer in 1782.
How do you tell how hot or cold something is?
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.
How does thermometer liquid?
When temperature goes up the liquid expands. The liquid then takes up more space and you see this as a rise in scale on the thermometer. The same applies vise versa
How does liquid thermometer work?
When temperature goes up the liquid expands. The liquid then takes up more space and you see this as a rise in scale on the thermometer. The same applies vise versa
How is a thermometer different from a number line?
On the negative side it is finite: the number line goes on forever in both directions.
What are the types of thermometer?
Celsius, Fahrenheit, and Kelvin.
What represents degree in thermometer?
Degrees on a thermometer represent temperature, which is a measure of the average kinetic energy of particles in a substance. As temperature increases, the particles move faster and the thermometer reading goes up. Each degree on a thermometer typically represents a specific amount of temperature change, such as one degree Celsius or Fahrenheit.
