How does the instrument used to measure air temperature differ from the instrument used to take your temperature?
Those thermometers use liquid crystals to measure temperature. More specifically, they use chiral nematic liquid crystals--long asymmetric molecules that arrange themselves in orderly spirals in the liquid. When light strikes these spiral structures, some of it reflects. But the reflection is strongest when the light's wavelength is an integer or half integer multiple of the spiral's pitch--the distance between adjacent turns of the spiral. Since light's wavelength is related to its color, the light reflected by these liquid crystals is colored. Because the pitch of a chiral nematic liquid crystal changes with temperature, so does its color. Slightly different liquid crystals are inserted behind each number on the thermometer so that each number becomes colored at a different temperature. copied from: http://rabi.phys.Virginia.edu/HTW/thermometers_and_thermostats.html
How is air temperature measured accurately?
Air temperature is measured accurately using a device called a thermometer. The thermometer is placed in the air and measures the temperature by detecting the expansion or contraction of a liquid or metal inside it. This provides an accurate reading of the air temperature at that location.
Does thermometer measure heat or temperature?
Different thermometers make use of different physical properties, that change with temperature - for example, volume, electrical resistance, and others. The basic household thermometer simply has a liquid - previously mercury, nowadays usually colored alcohol - that expands when it is heated.
A metal that is a liquid at room temperature?
Mercury. is the only metal that is liquid at room temperature.
What is only metal liquid at room temperature?
its a metal richardMercury is a liquid metal at room temperature .
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.
What is the the name of the object a thin glass tubbed filled with liquid that measures temperature?
Thermometer
An object which measures temperature?
A thermometer is an instrument used to measure temperature. It typically consists of a bulb containing a liquid (such as mercury or alcohol) that expands and contracts with temperature changes, which is then converted into a numerical temperature reading on a calibrated scale.

What does a thermometer do to measure temperature accurately?
A thermometer measures temperature accurately by using a liquid, such as mercury or alcohol, that expands or contracts based on the temperature. This causes the liquid to rise or fall in a narrow tube, which is marked with a scale to show the temperature.
What is the temperature of the waters in Antarctica?
So long as the water remains liquid, the temperature measures between 27 and 32 decrees F.
Ho does a thermometer measure temperature?
A thermometer measures temperature by using a substance that expands or contracts with temperature changes, such as mercury or alcohol. As the substance heats up or cools down, it moves along a scale marked on the thermometer, providing a reading of the temperature.
How does a mercury thermometer measures temperature?
A mercury thermometer measures temperature based on the expansion or contraction of the liquid mercury inside the narrow tube. As temperature rises, the mercury expands and travels up the tube, indicating a higher temperature, and vice versa. The temperature reading is taken at the point where the mercury level stabilizes.
How does a liquid-filled thermometer measure temperature accurately?
A liquid-filled thermometer measures temperature accurately by using the principle that liquids expand or contract with changes in temperature. As the temperature increases, the liquid inside the thermometer expands and rises up the tube, providing a visual indication of the temperature. Conversely, as the temperature decreases, the liquid contracts and moves down the tube. The markings on the thermometer scale correspond to specific temperature values, allowing for accurate measurement.
How does a glass stem thermometer measure temperature?
A glass stem thermometer measures temperature by using the principle of thermal expansion. The liquid inside the glass stem expands or contracts with temperature changes, causing the level of the liquid to move up or down the scale. This movement indicates the temperature.
how can the boiling point of the distillate be used to identify a substance?
This method is used whenever there is enough of the compound to perform a distillation. The distillation method of boiling point determination measures the temperature of the vapors above the liquid. Since these vapors are in equilibrium with the boiling liquid, they are the same temperature as the boiling liquid.
What does gradulated cylinder measures?
It measures the volume of a liquid
