Which poisonous metal was once used in thermometers due to its properties of expansion In heat?
Mercury.
Why does the thermometer go down when the temp gets cold?
A thermometer measures temperature based on the expansion or contraction of the liquid or metal inside it. When it gets cold, the molecules inside the thermometer contract, causing the liquid or metal to shrink, which in turn results in the reading on the thermometer going down.
What does a bimetal thermometer do?
A bimetal thermometer is two strips of different metals that have been stuck together. because the two metals will have differing rates of expansion under heat, the strip will bend towards one side. if the thermometer is colder than standard temperature, the strip will bend towards the side with a higher expansion rate, and if it is hotter, than it will bend towards the metal with the lower expansion rate. Because the expansion is a fixed property of a metal, a bimetal thermometer will have a relative accuracy because of them.
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.
Is Mercury a metal or a non metal?
Mercury is a metal , with all the properties of a metal except it is a liquid at room temperature.for ex when we use a thermometer we found mercury in liquid form. it is a metal
What is an example of thermal expansion that you have observed in your daily life?
an example would be a thermometer. A thermometer because it has mercury in it. When you check a patients temperature with a thermometer ,the heat from the patients body will cause the expansion of the mercury and the mercury flows in the tube. It stops at a point and that point indicates the temperature in the patients body.
Which poisons metal was once used in the thermometer -1lead 2neon 3 plutonium?
Neon is neither poisonous nor a metal. However, if I were making a thermometer, I'd be more likely to use it than either of the other two. Are you sure you didn't leave out one of the options?
What is the sSensor in Mercury-in-glass thermometer?
The sensor in a mercury-in-glass thermometer is the glass bulb at the base of the thermometer containing the mercury. The temperature is measured by the expansion or contraction of the mercury based on the surrounding temperature, allowing the thermometer to provide a temperature reading.
What liquid metal is most commonly used in thermometer?
The liquid metal in many thermometer is mercury (Hg).
What is a thin glass tube with bulb on one end that contains a liquid?
Thermometer. They contain Mercury which is a metal.
What are the Sources of errors in liquid metal thermometer?
Sources of errors in liquid metal thermometer include inaccurate calibration, improper immersion depth of the sensor in the liquid metal, variations in the composition of the liquid metal affecting its thermal properties, and external factors such as ambient temperature fluctuations or vibrations affecting the reading.
Are the properties in a compound always the same as the properties in the elements in the compound?
Not always. For example sodium (Na), a metal that reacts violently with water, and chlorine (Cl), a yellow poisonous gas, combine to make table salt, which has none of these properties. But in others cases there are some similarities, like in a metal alloy.
