If we look matter at microscopic level, temperature is no other thing that the average molecules or atoms energy due to their random motion.
The fact that temperature is not measured in energy units (Jouls) is only a matter of how historically the measure of temperature was born and, if needed, temperature can be measured in energy units by multiplying the measure in absolute degrees (°K) by a constant called Boltzmann constant.
When a hot piece of matter (that is a piece of matter with fast molecules) is put in contact with a cold piece of matter (that is a piece of matter with slow molecules) collisions between the molecules of the two bodies tends to accelerate the slow molecules and decelerate the fast once. This is seen as cooling the hot body and heating the cold one.
Moreover, particles with a certain energy tends (for a complex quantum mechanical mechanism) to emit light whose frequency is strictly related to the body temperature. As a matter of fact, observing a body emitting light (not reflecting light emitted by another body like objects reflecting sun light) we can deduce its temperature from the color of the emitted light. All the bodies on earth are around 25°C (really in between -30 and 50) and emits in the near infrared. It cannot be seen by eyes, but it can be revealed by infrared glasses (that are generally called night viewers) so that infrared light emitted by objects allows us to use night viewers to see in the absence of sun light.

What is a natural sources of light?
The sun is an example of natural source of light. Thanks for asking.
What device produces heat automatically when it senses that there is no light and no heat?
A thermal circulator or an electric heater with a built-in thermostat can automatically produce heat when it senses the absence of light and heat. These devices can turn on when the temperature drops below a certain threshold to provide warmth in the absence of natural light or heat sources.
What are Example of natural source of heat and light?
Examples of natural sources of heat and light include the Sun, which provides sunlight and warmth essential for life on Earth, and fire, which can occur naturally through wildfires or volcanic activity. Additionally, geothermal energy from the Earth's interior can produce heat, while bioluminescent organisms, such as certain types of jellyfish and fireflies, emit light through natural chemical processes. These sources play crucial roles in ecosystems and influence climate and weather patterns.

Examples of heat sources?
Examples of heat sources could be grouped into two (2) based on there origin. They are; 1. Natural Heat Sources. The natural heat sources could be sub-divided into two; a. External Source, e.g Sun. b. Internal Source, e.g Geothermal, i.e. Magma. 2. Man-made Heat Sources. These includes heat generated from; a. Electricity, e.g Electric Cooker and Oven. b. Fire, e.g Coal.
What are the three natural sources of heat and light?
The three natural sources of heat and light are the sun, fire, and lightning. These sources provide heat and light through processes such as nuclear fusion, combustion, and electrical discharge.
Are the stars natural sources of heat and light?
Yes, stars are natural sources of heat and light. They generate energy through nuclear fusion in their cores, which produces heat and light that radiates into space, including the light that we see from Earth.
What is a natural sources of light?

What are 2 categories of heat sources?
Two categories of heat sources are natural heat sources and artificial heat sources. Natural heat sources include the sun, geothermal energy, and volcanic activity. Artificial heat sources include electric heaters, gas heaters, and oil heaters.

What are the artificial heat sources of heat and light?
Artificial heat sources include electric heaters, gas furnaces, and wood-burning stoves. Artificial light sources include incandescent light bulbs, fluorescent lights, and LED lights.

Where do you get heat and light?
Heat and light can be generated from various sources such as the sun, fire, electricity, or chemical reactions. The sun is the primary source of both heat and light for Earth, while artificial sources like light bulbs and heaters use electricity to produce heat and light.
