The official definition of the word bolometer is "a sensitive electrical instrument for measuring radiant energy."
Langley
A Bolometer.

The simple answer is by looking at them.The technical answer is by analysing their bolometric luminosity with a bolometer.
A thermometer can measure body Temperature. A bolometer measures heat radiation. A calorimeter determines quantities of heat.
optical pyrometerA special type of technique is used to measure very high temperatures such as the Sun. A Bolometer is the instrument used to measure the Suns temperature. The Bolometer measures in colors, and the Sun emits temperatures in colors. This technique is based on a law called Wien's Law.
A pyrometer is an instrument that measures heat radiation. It works by detecting the infrared radiation emitted by an object to determine its temperature. It is commonly used in industrial settings to monitor and control high-temperature processes.
A calorimeter measures heat. In contrast, a thermometer measures temperature.A thermometer bolometer - an instrument that measures heat radiation; extremely sensitive calorimeter - a measuring instrument that determines quantities of heatHeat is measured with a ThermometerThermometerThermometer or calorimeterThermometerthermometerHeat is measured with a thermometer.
All objects on Earth emit IR radiation, or heat, which can be detected by electronic sensors, such as those used in night-vision goggles and infrared cameras. A simple example of such a sensor is the bolometer, which consists of a telescope with a temperature-sensitive resistor, or thermistor, at its focal point
Yes, a radiation pyrometer is able to measure the temperature of the sun. Radiation pyrometers work by measuring the infrared radiation emitted by an object, and the sun emits enough infrared radiation that it can be accurately measured using a pyrometer.
A thermometer is commonly used to measure heat. It works by detecting changes in temperature and displaying the results on a scale. There are various types of thermometers, including digital, infrared, and mercury thermometers, each with its own method of measuring heat.
According to SOWPODS (the combination of Scrabble dictionaries used around the world) there are 2 words with the pattern B-L-M-T--. That is, nine letter words with 1st letter B and 3rd letter L and 5th letter M and 7th letter T. In alphabetical order, they are: bolometer bolometry
