How are heat and light produced in the sun
WebThe outside of the sun (its surface) is covered with very hot gases. The different gases mix together and cause reactions that are called nuclear reactions. Nuclear reactions create a lot of energy, which makes the sun very hot. The heat creates a lot of light too. Did you know that the sun is so bright that it will damage your eyes if you look ... WebFire is what we call the heat and light produced when things burn. Magnesium reacts with oxygen to make a compound called magnesium oxide. 2Mg + O 2---> 2MgO. The bright light results because this reaction produces a lot of heat. When the magnesium gets really hot, it emits energy in the form of light (heat is also how the sun produces light).
