How do you read the temperature on a Galileo thermometer?
To read the ambient temperature on a Galileo thermometer is very easy. What you have to do is simply look at the lowest ball that is floating while ignoring those tags that had sunk to the bottom of the container. It's those balls that float or are neutrally buoyant that interest us.
How did Galileo thermometer work?
Galileo thermometers work on the principle of buoyancy, which determines whether objects float or sink. As the temperature changes, the glass balls will either sink to the bottom (temperature rises), or float to the top (temperature falls).
How accurate is the Galileo thermometer?
The Galileo thermometer is a decorative instrument that measures ambient temperature, and unlike the Fitzroy storm glass—it is reasonably accurate. We think it's an excellent option for those looking for a unique gift for a weather enthusiast.
What liquid is inside a Galileo thermometer?
ethanol What is the clear liquid in a Galileo thermometer? The clear liquid in a Galileo thermometer is ethanol, a colorless volatile liquid with very little odor. Although its density is less than water, it varies depending on the temperature, even more so than water.
Where do you put the Galileo thermometer?
Hang your Galileo thermometer indoors and from a hook. For the most accurate results, it's best to not hang the thermometer in direct sunlight. Allow a few minutes for the floating spheres within the thermometer tube to rise and fall according to the current temperature.
How does a liquid in glass thermometer work?
Liquid-in-glass thermometers are based on the principle of thermal expansion of substances. A liquid in a glass tube (called a capillary) expands when heated and contracts when cooled. A calibrated scale can then be used to read off the respective temperature that led to the corresponding thermal expansion.
Are Floating thermometers accurate?
Floating or Standing Thermometers If your tank has large boisterous fish, this is not a wise choice for a thermometer. Another negative is that the scale is often in smaller print than other styles of thermometers, so is hard to read accurately.
Can Galileo thermometers explode?
Danger of explosion: Product does not present an explosion hazard.
How much water do you put in a storm glass?
The water should be about 1” up the spout of the Storm Glass. If the water is not at this level, fill the syringe with air and insert the filling tube back into the top of the water chamber. Do not turn the Storm Glass upside down for this procedure.
What are liquid thermometers filled with?
In a mercury thermometer, a glass tube is filled with mercury and a standard temperature scale is marked on the tube. With changes in temperature, the mercury expands and contracts, and the temperature can be read from the scale. Mercury thermometers can be used to determine body, liquid, and vapor temperature.

Is Galileo thermometer toxic?
Is Galileo thermometer liquid toxic? The liquid in AcuRite Galileo Thermometers is 100% paraffin. The colored bulbs are filled with paraffin and 3.4% dye. The liquid is non-toxic.
Do you shake a storm glass?
You can gently shake the glass every 5-10 minutes to move crystals around and speed up the process. Repeat the process until all crystals dissolve and the liquid inside the weather glass becomes completely clear. Once you reset your storm glass, dry it with a towel and let it cool down for 5-10 minutes.
Where should I place my storm glass?
Storm glasses are not intended for outdoor use, so if you purchase one, keep it indoors. They should also not be placed in a window that receives direct sunlight, or somewhere that may experience sudden temperatures changes during the day. Keep it away from walls facing the outside or near heating and cooling ducts.
How does a liquid thermometer work?
The way a thermometer works is an example of heating and cooling a liquid. 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.
What is the red liquid in a thermometer called?
How can I tell if my thermometer has mercury? Mercury is a silver-white to gray substance. If your thermometer is filled with a red liquid, your thermometer contains red dyed alcohol or mineral spirits and not mercury. These are safer alternatives to mercury fever thermometers.
Why does my storm glass not work?
Sometime due to shipping process weather glass can get “stuck” – Which results in crystals just sitting at the bottom and storm glass not working correctly. Crystals can stay that way for weeks, if not months, even when the weather drastically changes.
Does storm glass actually work?
This gave us a couple simple tests: the storm glass was clear or it wasn't; rain fell or it didn't. In the end, accuracy for individual glasses ranged from 45 to 54 percent, for an average of 49 percent.
How do you recharge a storm glass?
To reset your storm glass, carefully place it in a plastic container filled with mildly hot tap water and leave it there for about 20-40 minutes. You can gently shake the glass every 5-10 minutes to move crystals around and speed up the process.
How does a digital thermometer work without mercury?
Digital thermometers contain a device called a thermoresistor. The thermoresistor has an electrical current running through it, and the resistance, or how freely the current can flow, changes with temperature. A small computer or other circuit measures the resistance, and converts it to a temperature.
What happens if you touch mercury?
MERCURY EXPOSURE If it is swallowed, like from a broken thermometer, it mostly passes through your body and very little is absorbed. If you touch it, a small amount may pass through your skin, but not usually enough to harm you.
What replaced mercury in thermometers?
electronic digital thermometers There are several types of non-mercury-containing thermometers, including both liquid-in-glass and electronic digital thermometers. An example of an electronic digital thermometer is the platinum resistance thermometer. Others include the thermistor and the thermocouple.
Where should a storm glass be placed?
Storm glasses are not intended for outdoor use, so if you purchase one, keep it indoors. They should also not be placed in a window that receives direct sunlight, or somewhere that may experience sudden temperatures changes during the day. Keep it away from walls facing the outside or near heating and cooling ducts.
Why is my storm glass not working?
Sometime due to shipping process weather glass can get “stuck” – Which results in crystals just sitting at the bottom and storm glass not working correctly. Crystals can stay that way for weeks, if not months, even when the weather drastically changes.
Which is more accurate digital thermometer or mercury thermometer?
Both laboratory and clinical studies show that there is no significant difference in the average accuracy of the two types of thermometers, however there is a greater fluctuation of readings of temperature when using electronic thermometers.
Can you still buy mercury thermometers?
While mercury thermometers can measure temperature within one degree Celsius, digital thermometers can be as accurate as 0.001 degrees C a difference of four orders of magnitude in accuracy. This changeover won't be a big deal for the average person "In fact, you can't buy (mercury thermometers) anymore," Strouse said.
How do you rid your body of mercury?
The traditional treatment for mercury poisoning is to stop all exposures. In many cases, chelation therapy is also used. This involves giving a medication (the chelator) which goes into the body and grabs the metal (chelos is the Greek word for claw) then carries the metal out of the body, usually into the urine.
What is the blue liquid in thermometers?
The blue spirit thermometers listed contain non-toxic isoamyl benzoate and dye. These thermometers can be stored horizontally; their separation rate is equal to or better than mercury thermometers.
Should you shake a storm glass?
You can gently shake the glass every 5-10 minutes to move crystals around and speed up the process. Repeat the process until all crystals dissolve and the liquid inside the weather glass becomes completely clear. Once you reset your storm glass, dry it with a towel and let it cool down for 5-10 minutes.
Why does my digital thermometer give me different readings?
Differences between measurements can also result from the following factors: The thermometer is not the same temperature as the room you are measuring in (Example: it has been in a much warmer or colder room). The thermometer is inserted into the ear canal at a different depth or angle.
