The instrument used to measure temperature is usually the thermometer, although a thermistor can also be used. Learn about the way in which a thermometer works on the basis of liquid expansion with help from a science teacher in this free video on physical science.
Also to know is, what is the instrument used to measure the air temperature?
Measuring Humidity; A Psychrometer is an instrument used to measure relative humidity. It traditionally consists of two thermometers, one covered with a wet cloth. Evaporation cools this thermometer below the actual air temperature, recorded on the dry thermometer.
What is the name of the instrument used to measure heat?
An outdoor thermometer used to measure the average thermal energy in the air. A thermal infrared camera used to image heat. . Heat is measured in quantities called joules (pronounced the same as jewels) in the metric system and in British Thermal Units (BTU) in the English system. Heat can also be measured in calories.
Which device is used to measure the temperature of sun?
Pyrometer. Pyrometer, device for measuring relatively high temperatures, such as are encountered in furnaces. Most pyrometers work by measuring radiation from the body whose temperature is to be measured. Radiation devices have the advantage of not having to touch the material being measured.
