A thermometer works by using a substance, like Mercury or alcohol, that expands or contracts with temperature changes. This substance is contained in a sealed tube with markings to show the temperature. When the temperature rises, the substance expands and moves up the tube, indicating a higher temperature. When the temperature drops, the substance contracts and moves down the tube, showing a lower temperature. This allows the thermometer to accurately measure temperature changes.

How does mercury work in a thermometer to measure temperature accurately?
Mercury in a thermometer expands and contracts with changes in temperature. As the temperature rises, the mercury expands and rises in the tube, and as the temperature falls, the mercury contracts and lowers in the tube. This movement is then converted into a temperature reading on the scale of the thermometer, allowing for accurate temperature measurement.
How does a thermometer work to measure temperature accurately?
A thermometer works by using a substance, such as mercury or alcohol, that expands or contracts based on temperature changes. This substance moves up or down a calibrated scale to indicate the temperature. The accuracy of the measurement is determined by the precision of the scale and the sensitivity of the substance to temperature changes.
What is a probe thermometer?
this is a thermometer that can work twice as much as a normal thermometer or a thermometer that can check the temperature of two things at the same time
How do infrared thermometers work on water?
Infrared thermometers work on water by measuring the temperature of the water based on the infrared radiation it emits. Water absorbs and emits infrared radiation, allowing the thermometer to accurately measure its temperature without direct contact.
What is the working principle of the mercury thermometer?
Mercury thermometers work on the principle that mercury expands when heated and contracts when cooled. The scale on the thermometer is calibrated based on this expansion and contraction, allowing it to measure temperature accurately. When the temperature rises, the mercury expands and rises up the tube, and when the temperature falls, the mercury contracts and moves back down the tube.

How do you measure temp of room without a thermometer I only have a digital oral thermometer?
It is not possible to measure the room temperature with a thermometer. A digital oral thermometer will not work to measure the room temperature. It is meant to measure human temperature, not room temperature. You will need a room thermometer to measure the room temperature.
Could a thermometer work at 115 degrees?
Most common thermometers can measure temperatures up to 120-130 degrees Fahrenheit, so a thermometer should be able to work at 115 degrees Fahrenheit. However, it's always best to check the specifications of the thermometer to ensure it can accurately measure temperatures at 115 degrees.
What does a thermometer measure and how does it do it?
A thermometer is a device that measures temperature or temperature gradient using a variety of different principles. The word temperature comes from the Greek work thermo which is heat and meter to measure.
When did John Harrison invent the bimetal thermometer?
John Harrison invented the bimetal thermometer in the early 18th century, with his work on it taking place around 1750. This innovative device utilized two different metals that expand at different rates to measure temperature accurately. Harrison's invention was significant in the development of more precise temperature measurement tools.
How does a temomether work?
A thermometer works by measuring temperature through a physical property that changes with temperature, such as the expansion of a liquid (mercury or alcohol) or a metal coil. When the temperature changes, the property changes, leading to a corresponding movement of the indicator on the thermometer scale. This allows us to read and interpret the temperature accurately.
What are the disadvantages of using a water-in-glass thermometer to measure outside air temperature?
Well it won't work below freezing.
Tool used to measure the temperature?
Whilst a thermometer may give an 'estimated' readout of which can be right within a few percent of the actual value, this is not very accurate at all. There are of course several different types of thermometers. Some made with quicksilver. Others made with alcohol. With the development of transistors, we started to develop electronic thermometers of which can work in many different ways. they can measure infrared radiation. they can measure intensity and spectrum of light. they can measure with probes of various metals. The art of measuring temperature is a difficult one. Most thermometers only work accurately within a short range. You would for instance not use a thermometer filled with quicksilver or alcohol in order to measure the temperature in a pot of molten lead! First you need to narrow down the field, then you can begin with the right (mostly costly) thermometer for the task. A piece of copper wire can be used in order to measure temperature between -200 and + 150 degrees Celsius. We know that the resistance in copper changes with a certain percentage per degree Celsius. With a bit of calculations we will be able to calculate the temperature to almost perfection if we only know the exact dimensions of the copper wire used. Whilst our best mathematical efforts show possibilities, we still have to be sure that we measure the resistance to a very high degree of perfection too, but this is another subject.
