What does a thermometer contain water or Mercury?
If it's a silver liquid it's mercury, if it's red it's alcohol (not water)
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.
This instrument is often filled with mercury colored water or alcohol?
The instrument you are referring to is likely a thermometer. Thermometers are commonly filled with either colored alcohol or mercury to measure temperature changes based on the expansion or contraction of the liquid inside.
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
What is the clear liquid inside a Galileo thermometer?
The clear liquid inside a Galileo thermometer is typically a hydrocarbon-based liquid, such as ethanol or mineral oil. This liquid expands and contracts with temperature changes, causing the glass spheres with different densities to float or sink.
What happens to the mercury level when the cold thermometer is kept in a hot tub of water?
The mercury level in a thermometer placed in a hot tub of water will rise as the temperature of the water increases. This is because the volume of liquid mercury expands with higher temperatures, causing it to climb up the measuring scale in the thermometer.
Who made the first water thermometer?
Galileo Galilei invented the first water thermometer. He created it by adding droplets of alcohol in the water. This is so the liquid is less denser and can detect changes in temperature.
Why is the water not used in the construction of liquid in glass thermometer?
Water expands unevenly when heated and can freeze at low temperatures, affecting the accuracy of the thermometer. Mercury, which is used in liquid-in-glass thermometers, expands evenly with temperature changes and remains liquid at a wide range of temperatures, making it ideal for measuring temperature accurately.
Which matter remains liquid at room temperature?
Mercury is the only metal that remains liquid at room temperature.
What will the mercury thermometer show when it is kept in ice?
The question must be asked carefully. If the thermometer is in water ice and there is no liquid water, and there is one atmosphere of pressure, the thermometer can read anything from the freezing point of water and lower, depending on the range of the thermometer. If the thermometer is in a stable mix of water and ice, it will read the freezing point of water.
Which liquid will boil last water or mercury or alcohol?
Mercury will boil last, as it has a higher boiling point than water and alcohol. Mercury boils at around 674 degrees Fahrenheit, while water boils at 212 degrees Fahrenheit and alcohol at about 173 degrees Fahrenheit.
Which thermometer is most suitable for measuring boiling point of water mercury or alcholic thermometer?
Which thermometer is most suitable for measuring boiling point of water mercury or alcoholic thermometer
