How does the 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 a Galileo thermometer?
There is also the minor detail that Galileo thermometers are not exactly precision instruments. A small one can have 6 degrees (F) of difference between the balls, which make for quite a measurements range of error. Even larger models have at least a couple of temperature difference between the diver globes.
How do you read a thermometer correctly?
Most thermometers have two scales for temperature, Fahrenheit and Celsius. Read the numbers for °F (degrees of Fahrenheit). Each long line is for 1°F temperature. The four shorter lines between each long line are for 0.2°F (two tenths) of a degree of temperature.

For example this mark is 99 this mark is 101MoreNumbers these represent the odd whole number values. For example this mark is 99 this mark is 101 this mark is 103. And so forth. So this temperature reading is 105 degrees fahrenheit.
What is the clear liquid in a Galileo thermometer?
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.
What’s the right body temperature?
Fevers usually don't need treatment. 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.
What should your normal temperature be?
The average normal body temperature is generally accepted as 98.6°F (37°C). Some studies have shown that the "normal" body temperature can have a wide range, from 97°F (36.1°C) to 99°F (37.2°C). A temperature over 100.4°F (38°C) most often means you have a fever caused by an infection or illness.
What is the liquid inside of a glass Galileo thermometer?
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.
What are the different liquids in a Galileo thermometer?
This thermometer is based on an invention of Galileo Galilei. The liquid in a Galileo thermometer is water. Floating in the water within the tube are glass bubbles also filled with water containing simple food coloring, though sometimes alcohol might be used.

Why does my body feel hot but no fever?
It's possible to feel feverish but not have a fever, and there are many possible causes. Certain underlying medical conditions may increase your intolerance to heat, while some medications you take can also be to blame. Other causes may be temporary, such as exercising in the heat.
What is a fever if you run low?
While body temperatures vary, most of us have an internal temperature around 98.6 degrees Fahrenheit. A temperature slightly higher than that is still normal. When your temperature is between 100.4 and 102.2, you have what is considered a low grade fever.
What body temperature is considered a fever?
Normal body temperature ranges from 97.5°F to 98.9°F (36.4°C to 37.2°C). It tends to be lower in the morning and higher in the evening. Most healthcare providers consider a fever to be 100.4°F (38°C) or higher.
Is 96.6 temp too low?
Hypothermia is a medical emergency that occurs when your body loses heat faster than it can produce heat, causing a dangerously low body temperature. Normal body temperature is around 98.6 F (37 C). Hypothermia (hi-poe-THUR-me-uh) occurs as your body temperature falls below 95 F (35 C).
How do you read a weather glass?
Description
- If the liquid in the glass is clear, the weather will be bright and clear.
- If the liquid is cloudy, the weather will be cloudy as well, perhaps with precipitation.
- If there are small dots in the liquid, humid or foggy weather can be expected.
- A cloudy glass with small stars indicates thunderstorms.
