How do you measure the temperature of an object?
The higher the temperature of an object, the higher is its kinetic energy. Kinetic energy is a type of energy associated with motion. Temperature is measured with thermometers, which are devices that use the expansion of a substance to give an indirect measure of temperature.
Which type of thermometer uses solid metal?
A bimetallic thermometer works by using two basic properties of metal: The thermal expansion property of the metal. The coefficient of thermal expansion of different metals is different for the same temperature.
What are four methods of measuring temperature?
The Four Types of Temperature Scales
- Fahrenheit Scale. ••• The Fahrenheit scale of temperature is the common form of temperature measurement used in the United States and some parts of the Caribbean.
- Celsius Scale. •••
- Kelvin Scale. •••
- Rankine Scale. •••
Where do we measure temperature?
Your body temperature can be measured in many places on your body. The most common ones are the mouth, the ear, the armpit, and the rectum. Temperature can also be measured on your forehead. Thermometers show body temperature in either degrees Fahrenheit (°F) or degrees Celsius (°C).
How do you calculate temperature?
However, the following general guidelines for temperature results are used: The average normal oral temperature is 98.6°F (37°C). A rectal temperature is 0.5°F (0.3°C) to 1°F (0.6°C) higher than an oral temperature. An ear temperature is 0.5°F (0.3°C) to 1°F (0.6°C) higher than an oral temperature.
What are the instrument for measuring temperature?
thermometers
A temperature meter is an instrument used to measure the temperature of beings or things. The most widely recognized temperature meter is a mercury thermometer used to measure the temperature of people. These thermometers consist of a graduated glass capillary with a pool of mercury in one end.
Which instruments are used to measure temperature?
Thermometer is an instrument used for measuring the temperature of a body.
How do you check temperature with a digital thermometer?
To use a digital thermometer:
- Clean the tip with cold water and soap, then rinse it.
- Turn the thermometer on.
- Put the tip under your tongue, towards the back of your mouth.
- Close your lips around the thermometer.
- Wait until it beeps or flashes.
- Check the temperature on the display.
How does a metal thermometer work?
Bimetal thermometers work on the principle that different metals expand at different rates as they are heated. By using two strips of different metals in a thermometer, the movement of the strips correlates to temperature and can be indicated along a scale.
How can I measure my temperature without contact?
You no longer need to touch an object with a probe to measure its temperature. Non-contact infrared temperature sensors (also known as pyrometers) are capable of measuring surface temperature with a much faster response time than thermocouples, and with similar or better accuracy.
What is the easiest way to measure the temperature of solids?
The easiest method is by calorimetry. Basically placing the solid in a liquid of the same temperature and allowing the system to arrive at a thermal equilibrium (which is at a temperature you can now measure with a simple thermometer thanks to the liquid.)
How do you measure solids in cooking?
In measuring solids, you need a measuring cup with a flat lip where you can move the back of a knife across the top of the measuring cup. If a recipe calls for one cup it means one level cup, one-half cup means one-half level cup, etc.
How do you measure the temperature of a powder?
Powders or granular solids can be stirred at a very high rate and can be treated in the same manner as liquids, but it is difficult to feel confident in the observed temperature. For bulk solid materials (like a metal cube), the temperature is measured indirectly by performing a calorimetry experiment.
How do you use a thermometer to find thermal equilibrium?
Thermometer. To heat a solid to a desired temperature, place the solid in a liquid or solution heated to the desired temperature and allow the system to reach thermal equilibrium (when the liquid or solution is the same temperature as the solid). Thermal equilibrium is observed when the temperature of the system does not change for several minutes.
