Why can a liquid mercury thermometer only be used between -40 and 360?
The range of -40 to 360 degrees Fahrenheit is within the melting point and boiling point of mercury, ensuring that the mercury remains in liquid form and does not solidify or vaporize. Outside this range, the thermometer would not function accurately as the mercury would either freeze or evaporate.
What is the scale on a thermometer to measure the temperature?
The scale is either Fahrenheit degrees or centigrade (Celsius, Kelvin) degrees. The Fahrenheit scale has 180 equal degrees between the freezing point of water (32°F) and the boiling point (212°F). On the Celsius scale, there are 100 equal degrees between these points (0°C to 100°C).
How does an air thermometer work?
An air thermometer has a bubble of liquid inside the tube and when the air inside of the tube heats up or cools down, the air takes up either more or less space inside of the tube, causing the bubble of liquid to either move upwards or downwards, indicating the temperature.
How does pressure affect a thermometer?
Heat is transferred thru the glass of the thermometer to or from the liquid (mercury) inside. The heat causes the liquid to either expand (hot) or contract. Since the large bulb end contains most of the liquid, but grass doesn't expand as much as the liquid, the expanding liquid forces itself up (if hot) into the narrow tube, which indicated the temperature. On the molecular level, particles outside the thermometer have a certain kinetic energy (KR) and the particles inside the thermometer also have a certain KE probably a different amount or they are already at the same temperature. Particles (either molecules or atoms) when in either the solid or liquid state, are constantly in motion (for solids, they just vibrate about a fixed, central position. Collision of the particles outside the thermometer and the thermometer itself cause exchange of some KE until the average KE of the outside particles is equal to the average KE of those in the thermometer. When this occurrs they are at the same temp. This change in KE of the particles in the thermometer causes more motion, and this extra motion causes what we call expansion. All molecules in the thermometer are pushing against each other with more force (KE).
Separating technics of salt water to clean water?
One commonly used technique is desalination, which removes salt and impurities from seawater through processes like reverse osmosis or distillation. These methods involve either forcing water through a special membrane that traps salts, or boiling water and collecting the clean condensation. Both methods can produce clean drinking water from saltwater sources.
How do you get your XBOX mic to not echo?
either refund it for a new one, recalibrate it ,or it might be bad connection
Which gas is used in gas thermometer?
Gas thermometers typically use either nitrogen or helium as the gas inside the thermometer. These gases are preferred due to their low boiling points and well-defined expansion and contraction characteristics with changes in temperature.
What instrument measures body temperature?
A thermometer is used to meusure your body temperature either it can be clinical thermometer or digital thermometer.
Why should a clinical thermometer not be sterilize in boiling water?
Because clinical thermometer have a very small range. (20 to 45 degrees Celsius at most) and if placed in boiling water, the water being 100 degrees will cause damage to the thermometer.
Is the Fahrenheit thermometer scale proportional to the Celsius thermometer scale?
There is nothing special about either scale
When do you insert meat thermometer before or after cooking?
unless your thermometer is designed to stay in the oven, check the temp when theturkey is nearly done.Most inexpensive grocery store thermometers are NOT designed to stay in the oven.
What is the index of a thermometer?
The index of a thermometer is the scale or numerical reference used to indicate temperature readings. It can be in either Celsius or Fahrenheit, depending on the type of thermometer.
Can you use a meat thermometer for foods other than meat?
Yea, why wouldn't you? It's still a thermometer either way.
What is inside the glass tube from a thermometer?
either mercury or alcohol
What thermometer would be used to collect data over a twenty four hour period of time?
You can use the recording thermometer or the mercury thermometer, either one of those will work.
What is it when a gas change to a liquid?
It can be called either boiling or evaporation.
How does impurities in water effect its boiling point?
Depending on what is in it, the boiling point will either rise or fall.
