What is the year the thermometer was made by Galileo?
Galileo Galilei did not invent the thermometer. The first modern thermometer, using mercury in a glass tube, was invented by Daniel Gabriel Fahrenheit in the early 18th century, around 1714.
What was the first liquid used in a thermometer?
The first liquid used in a thermometer was likely alcohol, specifically ethanol. Alcohol has a low freezing point and a wide range of expansion when heated, making it suitable for use in early thermometers.
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.
The liquid in a thermometer move up the glass tube when the air temperature?
The liquid in a thermometer rises in the glass tube when the air temperature increases due to thermal expansion. As the temperature rises, the liquid (usually mercury or alcohol) absorbs heat and expands, occupying more space and causing it to move upward in the tube. This movement allows the thermometer to accurately reflect the ambient temperature. Conversely, when the temperature drops, the liquid contracts and moves down the tube.
What is the apparatus of thermometer?
A typical thermometer consists of a glass tube filled with a liquid (usually mercury or alcohol) that expands and contracts with changes in temperature. The tube is usually marked with a scale for reading the temperature, and there may be a bulb at the bottom to sense the temperature.
Did gallilio gallili invented the thermometer?
No, Galileo Galilei did not invent the thermometer. The first modern thermometer was invented by Santorio Santorio in the early 17th century, using a tube filled with a liquid that expanded and contracted with temperature changes. Galileo did contribute to the development of thermometers by discovering the principle of buoyancy that makes them work.

What was the first liquid used in the first ever thermometer?
Water - Galileo Galilei invented a rudimentary water thermometer in 1593 which, for the first time, allowed temperature variations to be measured
Which Italian astronomer invented the thermometer in 1592?
Galileo Galilei was the first to invent the thermometer formerly known as thermoscope in 1592.
Who invented the first test tube?
John Flamsteed invented the first test tube.
How invented the outdoor thermometer?
The first outdoor thermometer was invented by Galileo Galilei in the early 17th century. He used a glass tube filled with a liquid, typically alcohol, that would expand and contract with temperature changes, indicating the temperature on a scale.
How did Galileo invent the thermometer?
He did not actually invent the thermometer, which would have shown a scale of temperatures. He invented the "thermoscope" -- a device that showed increase or decrease of temperature using the expansion of a liquid in a tube.
Who first invented the cathode ray tube?
The cathode ray tube was invented in 1897 by Ferdinand Braun.
Who element used of the glass tube of clinical thermometer to measure thermometer?
mercury
Who invented the Mercury thermameter?
A mercury-in-glass thermometer, invented by German physicist Daniel Gabriel Fahrenheit, is a thermometer consisting of mercury in a glass tube. Calibrated marks on the tube allow the temperature to be read by the length of the mercury within the tube, which varies according to the heat given to it. To increase the sensitivity, there is usually a bulb of mercury at the end of the thermometer which contains most of the mercury; expansion and contraction of this volume of mercury is then amplified in the much narrower bore of the tube. The space above the mercury may be filled with nitrogen or it may be less than atmospheric pressure, which is normally known as a vacuum.
