What is the coloured substance used in thermometer?
The colored substance commonly used in a thermometer is typically either dyed alcohol or a non-toxic organic liquid like mercury. These substances expand and contract with changes in temperature, allowing the thermometer to measure temperature variations.
How is mercury in a thermometer poisonous?
Mercury in a thermometer is poisonous if it is inhaled or ingested. When a thermometer breaks, mercury vapor can be released into the air, which can be harmful if breathed in. Additionally, if mercury is ingested, it can be absorbed into the bloodstream and cause poisoning.
What are the two substances used in a liquid column thermometer?
The two substances used in a liquid column thermometer are mercury and alcohol. Mercury thermometers use mercury as the liquid inside the glass tube, while alcohol thermometers use colored alcohol such as ethanol or dyed ethanol.
Is it a solid liquid or gas found in a thermometer?
Actually anything that won't freeze or boil at the operating range of the thermometer. The most common are mercury and alcohol.
What is the name of the silver metal in a thermometer?
The silver-colored liquid inside a thermometer is typically mercury, which is a heavy metal that expands and contracts with changes in temperature, allowing the thermometer to measure and display the temperature accurately.
What is Mercury thermometer use to measure?
A mercury thermometer is used to measure temperature.
What liquids are used in thermometer?
Mercury and alcohol
Why does Mercury in the the thermometer rise?
Mercury rises in a thermometer when the temperature increases because mercury expands as it heats up. This expansion of the mercury column inside the thermometer is used to measure the temperature of the surrounding environment.
Why can a mercury thermometer be used only at high temperatures?
A mercury thermometer can go down to -30 deg C
Who element used of the glass tube of clinical thermometer to measure thermometer?
mercury
How is mercury used in a thermometer?
toxic poison
What is the mercury called on a clinical thermometer?
The liquid in a clinical thermometer is called mercury. It is used to measure body temperature by expanding and rising within the thermometer.
What color is the Mercury in a Mercury thermometer?
Mercury in a Mercury thermometer is typically silver in color.
Why does the mercury in the thermometer go up when the temperature is high?
In a mercury thermometer, the mercury expands when it is heated, causing it to rise in the thermometer's narrow tube. This increase in volume is a physical property of mercury known as thermal expansion. The height of the mercury column in the thermometer is then used to measure the temperature.
What element is often used as the liquid of thermometer?
Mercury
What are the two liquid used in the thermometer?
iodine and Mercury
Why not mercury thermometer is used to measure temperature of hot milk?
It could be used to do this - it is capable of doing it. However, Mercury is poisonous and a mercury thermometer is made out of fragile glass. Thus the danger that the thermometer would break releasing mercury into the milk (which would be for a person to drink) means that a mercury thermomiter is not the temperature sensor to use in this instance.
