How To Read Galileo Temperature?
The temperature can be measured by reading the metal tag attached to the lowest of the floating balls in the top half of the thermometer. Galileo thermometers work on the principle of buoyancy which determines whether objects float or sink.
How do you read a temperature tube?
How do you read a glass barometer?
Luckily it’s also simple to read. To determine the likely weather you have only to see how high or low the water is in the glass. Look at the water in the spout of the barometer. If the water holds steady around the middle of the spout you’ll have good weather.
How does Galileo explain heat?
� But Galileo took heat to be a sensation that exists only in sentient creatures so that a stone piece of iron or stick could not under any circumstances be said to be heated. � At best such objects could be made to move in such a way as to cause the sentient creatures that touch them to feel the sensation of heat.
What is Galileo thermometer filled with?
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. The dye inside colored bulbs may stain fabric.

What qualities does Galileo think belong to bodies themselves?
Galileo’s distinction between real or primary properties of material bodies—such as size shape position and motion or rest—which were thought to exist in bodies themselves and sensible or secondary properties—such as colours tactile feelings sounds odours and tastes—which were thought to exist only in the …
Where should a Galileo thermometer be placed?
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 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.

How do you fill a water barometer?
How to fill the weatherglass: Hold spout under tap and fill with a thin stream of water. The water level of the bottle itself should be approximately one inch (2.5cm) above the place where the spout joins the bottle. If used outdoors fill with rubbing alcohol during winter to avoid freezing.
How does liquid barometer work?
A water barometer or storm glass is used to predict stormy weather. It works because of changes in atmospheric pressure. … The top of the spout is above the water level and open. When air pressure sinks lower than when the body was sealed with water the water level in the spout rises above the level in the body.
How do you fill a barometer tube?
Dip a large syringe into the water and pull back the plunger to fill it. (Look for dental syringes meant for rinsing teeth and gums with warm water.) Push a 24-inch length of plastic tubing onto the end of the syringe and insert the other end of the tube into the spout of the water barometer.
How do you tell if a barometer is working?
Hold the instrument at the 45-degree angle and check the the level of the mercury in the glass tube with a long “stick” barometer. If the barometer is working correctly the mercury inside will rise quickly to fill the very tip of the tube leaving no air bubble.
What is a normal barometer reading?
A barometer reading of 30 inches (Hg) is considered normal. Strong high pressure could register as high as 30.70 inches whereas low pressure associated with a hurricane can dip below 27.30 inches (Hurricane Andrew had a measured surface pressure of 27.23 just before its landfall in Miami Dade County).
What should my barometer be set at?
To convert from hPa on the Met Office website to inches you will have to divide by 33.86. So for example if the Met Office observation shows 1013 hPa then you should set your barometer to 1013/33.86 = 29.92 inches or as close as possible to this.

What is the difference between primary and secondary qualities According to Locke?
