How does a liquid thermometer show that you have a fever?
That type of thermometer has mercury in it, which is very heat sensitive. When used for taking a temperature, the heat from the body causes the mercury to rise. The amount the level of the mercury rises is determined by the body's temperature; the higher the temp, the higher the mercury rises.
Why does the mercury fall or rise in a clinical thermometer when it is taken out of the mouth?
A clinical thermometer measures the max temp of the human body due to the expansion of the mercury in the bulb, which flows past a kink in the column and rises in the graduated stem, to read the highest body-temp. Once it is removed from the body, the mercury stays at that level, and does not fall because it cannot flow back into the bulb -- the kink prevents the back flow. It has to be shaken vigorously, as you know, for us to get the mercury back; then it is ready to take the temp again.. Also, the temp cannot rise further on its own from the max reading because the mercury does not expand the moment the thermometer is taken out of the body. Incidentally, temp can be measured under the armpits and in the rectum also.
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 two items are in a thermometer?
A precision capillary tube with a graduated scale and a liquid such as mercury or alcohol that will expand as the temp increases.
What is a tool to mesure temp?
A thermometer is a tool used to measure temperature. There are various types of thermometers, such as digital, infrared, and mercury thermometers, that can measure temperature in different ways depending on the application.
What is the function of mercury in thermometer?
Mercury is used in a thermometer because it expands and contracts uniformly with temperature changes. This allows the thermometer to accurately measure and display the temperature of a substance or environment. Mercury has a high coefficient of thermal expansion, making it a suitable choice for this purpose.
How does a thermometer keep your home at a constant temperature?
It doesn't A thermometer doesn't keep your home at a certain temp. a thermometer tells the temp. of a place.
What measures temp?
thermometer
How can temp be measured?
thermometer
How is temp measured?
to check the temp. you have to stick a thermometer through it
What type of metal is liquid at room temperature?
Mercury in thermometers: they expand and shrink but are still liquids inside the thermometer. It is still considered a metal and it is liquid at room temp.
When a mercury therometer is heated the mercury expands and rises in the thin tube of glass What does this indicate about the relative rates of expansion for mercury and glass?
The fact that the mercury expands and rises in the thin glass tube when heated indicates that mercury expands more than glass when heated. This suggests that mercury has a higher coefficient of thermal expansion compared to glass.
