What happens when a thermometer goes down?
When the thermometer is cooled, the molecules move more slowly, get closer together, and move down the tube. Help students realize that the attractions the molecules in the thermometer have for each other remain the same whether the thermometer is heated or cooled.
What is the lowest temperature a thermometer can measure?
The zero point on the Kelvin scale is known as absolute zero. It is the lowest temperature that can be achieved.
At what temperature does a thermometer break?
"When a mercury thermometer breaks, the mercury spilled starts vaporising immediately in temperatures of 22-24 degrees Celsius. The vapours can be inhaled by anyone in the vicinity. It goes straight into the lungs and into the blood and the brain. It is very dangerous.
Can thermometer show wrong temperature?
If your device uses probes to detect temperature, inaccurate readings can be a sign that the probe is going to fail soon, and you may want to order a replacement. 100°+ Inaccuracy: It is likely that your probe has already shorted out and may begin displaying a letter code soon (such as LLL or HHH).
How do you make a thermometer go down?
Grasp the Stem End Securely. Grasp the end of the thermometer that is opposite the bulb end with your fingers and thumb. The stem ends in a knob (usually colored either blue or red) that helps you to hold onto the thermometer during the shaking down process.
What happens inside a thermometer when the temperature goes up?
As 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.
Why alcohol is used in thermometer?
Alcohol thermometers are used rather than mercury thermometers in very cold regions because alcohol has a lower freezing point than mercury. Pure ethanol freezes at -115 degrees C, while mercury freezes at -38 degrees C. ... Since alcohol is colorless a dye is added.
Why mercury is used in thermometer?
Mercury is the only one in liquid state at room temperature. It's used in thermometers because it has high coefficient of expansion. ... It also has a high boiling point which makes it very suitable to measure higher temperatures. Also, it has a shiny appearance and doesn't stick to the glass surface of glass.
Do you think the temperature can keep dropping indefinitely explain your reasoning?
But this cannot go on forever. At one point, the particles have to stop moving, and this corresponds theoretically to the coldest possible temperature. You cannot go colder than that – this explains the existence of a minimum possible temperature.
What happens if you drop a mercury thermometer?
Mercury is a liquid metal with properties different from most substances. Small droplets will combine into a larger sphere shape, which will roll on a flat surface and break back into smaller droplets if dropped or if pressure is applied.
What should you do if you spill mercury?
Sprinkle sulfur powder over the contaminated area and rub it gently all over the surface and into the cracks with a paper towel. Sulfur powder binds with mercury. Use a paper towel dampened with water followed by wiping with another damp paper towel to clean up the sulfur and mercury.
Do thermometers freeze?
Answer: The thermometer is filled with parafin oil, which is similar to kerosene. It will NOT freeze or break.
Is 37.5 a fever?
An adult probably has a fever when the temperature is above 99°F to 99.5°F (37.2°C to 37.5°C), depending on the time of day.
How do I know if thermometer is accurate?
The ice bath test is the easiest way to test a thermometer for accuracy, assuming your thermometer will display temperatures of 32°F or less. The advantage of this method is that an accurate thermometer will always read 32°F in a properly made ice bath regardless of altitude or atmospheric pressure.
What body temp is normal?
The average body temperature is 98.6 F (37 C). But normal body temperature can range between 97 F (36.1 C) and 99 F (37.2 C) or more. Your body temperature can vary depending on how active you are or the time of day.
