oven
Some examples of heat sources include the sun, stoves and ovens, heaters, fires, and electrical appliances like hair dryers or toasters.
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.

Lamps or light fixtures with incandescent bulbs can provide both light and heat. Additionally, a fireplace or a stove can also function as sources of both light and heat in a home.
LED lights, fluorescent lights, and laser beams are examples of sources of light that produce minimal heat compared to incandescent bulbs or halogen lamps. These sources are more energy-efficient and are often favored for applications where heat generation needs to be minimized.
Examples of things that produce heat and light include the sun, a burning candle, a light bulb, and a campfire. These sources emit energy in the form of both heat and light through various processes such as combustion or nuclear fusion.
An ectothermic organism relies on external sources of heat to regulate its body temperature. Examples include reptiles, amphibians, and many invertebrates.
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.
Chemiluminescent light sources include glow sticks, fireflies, and the chemical reaction in a lightbulb. These sources produce light through a chemical reaction rather than heat or electricity.
Some common heat sources in an average home include furnaces, water heaters, stoves/ovens, electric heaters, fireplaces, and radiators. Each of these heat sources functions to provide warmth to different areas or appliances in the home.
Main sources of internal heat are Magmatism and Radioactivity.
