To calculate the Mercury rise in a thermometer, you need to subtract the initial temperature reading from the final temperature reading. The difference between these two readings represents the mercury rise in the thermometer. Make sure to use the units of measurement (usually degrees Celsius or Fahrenheit) in your calculation.
What else can I help you with?
Why will the mercury in the thermometer rise after 3 minutes?
The mercury in the thermometer will rise after 3 minutes because it expands when exposed to heat. As the thermometer absorbs the heat of the environment, the mercury inside it will expand and move up the tube, indicating a higher temperature.
What happen to the mercury when the bulb placed in hot water?
When a thermometer bulb containing mercury is placed in hot water, the mercury inside expands, causing the level of mercury to rise. This expansion of mercury is used to measure the increase in temperature accurately.
When the temperature increases the level of mercury in the thermometre rises why does this occur?
When the temperature increases, the molecules in the mercury inside the thermometer gain kinetic energy and move more rapidly. This increased movement causes the mercury to expand, leading to a rise in its level within the narrow tube of the thermometer. The expansion of the mercury is a result of its thermal expansion coefficient, which is a measure of how much a material expands or contracts with changes in temperature.
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.
Why the Mercury-in-glass thermometer first descends and then rise when put in flame?
When placed in a flame, the glass bulb expands rapidly. This increases the volume of the bulb and so the column descends. However, the glass then conducts the heat to the mercury so that it undergoes thermal expansion and the column rises.
What causes mercury in a thermometer to rise?
The mercury in a thermometer rises because of thermal expansion. When the temperature surrounding the thermometer increases, the molecules of the mercury expand, causing it to move up the narrow tube of the thermometer.
Why does the mercury not fall or rise in a clinical thermometer when taken out of the mouth?
Mercury does not fall or rise in a clinical thermometer when taken out from the mouth because of the KINK present in it.
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.
What happens to the mercury in a thermometer Why?
The mercury in a thermometer expands and contracts as temperature changes. This expansion and contraction causes the level of mercury in the thermometer to rise or fall, providing a visual indication of the temperature.
Why will the mercury in the thermometer rise after 3 minutes?
The mercury in the thermometer will rise after 3 minutes because it expands when exposed to heat. As the thermometer absorbs the heat of the environment, the mercury inside it will expand and move up the tube, indicating a higher temperature.
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 definition of Glass thermometer?
thermometer consisting of mercury contained in a bulb at the bottom of a graduated sealed glass capillary tube marked in degrees Celsius or Fahrenheit; mercury expands with a rise in temperature causing a thin thread of mercury to rise in the tube
The function of a Mercury thermometer?
A Mercury thermometer measures temperature by relying on the expansion and contraction of the liquid mercury inside the glass tube. As the temperature changes, the mercury expands or contracts, causing it to rise or fall in the tube, indicating the temperature.
What will happen if you hold a mercury thermometer from its bulb?
If you hold a mercury thermometer from its bulb, the heat from your hand can cause the mercury to expand and rise in the tube, giving an inaccurate reading. Additionally, mercury is toxic, so it is not safe to handle a broken thermometer. Always handle thermometers by the plastic casing to avoid these issues.
What happen to the mercury in a thermometer when the temperature increase?
When the temperature increases, the mercury in a thermometer expands and rises up the column because the volume of the liquid increases with temperature. This expansion is linear and is used to indicate the rise in temperature on the thermometer scale.
Why does mercury level goes down for a very short time when a mercury-in glass thermometer is placed in hot water?
The exterior of the bulb of the thermometer expands first, resulting in the mercury level to go down. After that the mercury in the bulb expands more than the glass bulb, resulting in the subsequent rise of the mercury level.
What makes mercury go up and down a thermometer?
the heat and temperature that causes it to rise and fall.
