What liquid metal is most commonly used in thermometer?
The liquid metal in many thermometer is mercury (Hg).
Which metal is used in clinical thermometer?
Mercury is used in clinical thermometers.
What is the measurement of theormeter?
A thermometer is used to measure temperature by the movement of a substance called mercury inside a sealed tube
How does a liquid thermometer measure temperature?
The alcohol or mercury in a thermometer expands or contracts very precisely according to heat or cold.
Why is there a need for us to shake the clinical thermometer prior to each use?
If the clinical thermometer is a mercury based thermometer, it needs to be shaken down prior to each use. This is because there is a pinch point between the mercury reservoir bulb and the capillary tube, to ensure that the mercury does not shrink back into the bulb after the temperature has been taken. The mercury has therefore to be shaken back into the bulb before another measurement can be made. One should note that in many countries use of mercury based clinical thermometers is now discouraged (because mercury is toxic) and electronic thermometers are used in stead - these do not need shaking.
What is thermometric substance?
These are materials used in thermometer whoses property varies with temperature
What is thermometric liquid?
Thermometric liquid is a liquid used in thermometers to measure temperature changes. Common examples include mercury and colored alcohol, which expand or contract in response to temperature variations, allowing for precise readings. The choice of thermometric liquid depends on the temperature range and the desired accuracy of the thermometer. Mercury is often used for high-temperature measurements, while alcohol is favored for lower temperatures due to its lower freezing point.
What is a thermometric substance?
A thermometric substance is a material that is used in a thermometer to measure temperature. It undergoes a physical change in response to temperature variations, allowing for the quantification of temperature. Common examples include mercury, alcohol, and bimetallic strips. The choice of thermometric substance depends on factors such as accuracy, range, and ease of use in a particular application.
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 is the name of the liquid in a thermometer?
The red liquid in a liquid-in-glass thermometer is mineral spirits or ethanol alcohol mixed with red dye. A grey or silver liquid inside the thermometer is mercury. Mercury thermometers are not used anymore due to the dangers associated with mercury.
What are thermometric substance and example?
Thermometric substances are materials that are sensitive to changes in temperature and can be used to measure it. Examples include mercury, alcohol, and liquid crystal.
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
Why is the mercury used as a thermometric substance?
Its High boiling pointIts low melting pointIt does not stick any glass
Who element used of the glass tube of clinical thermometer to measure thermometer?
mercury
