Why don't sparklers burn you? i don't understand if they're hot then how do they have little heat? and were learning about electric forces so it must have something with that
Sparklers produce light by means of an electroluminescent reaction. A chemical reaction excites an electronically excited state, which relases a photon of light. Although sparklers may appear "white hot", they are not. Glow sticks operate similarly.
To understand why sparklers don't burn you, it's important to differentiate between temperature and heat. While sparklers can reach high temperatures, they have little heat because heat is dependent on both temperature and time.
Sparklers are made up of a metal wire coated in a mixture of chemicals that produce a glowing effect when burned. These chemicals can reach temperatures up to 1800 degrees Fahrenheit (980 degrees Celsius), which is very hot. However, because the combustion occurs on the surface of the sparkler and is short-lived, the time the heat is applied to your skin is minimal.
The small mass of the sparkler wire means it doesn't have enough thermal energy to transfer a significant amount of heat to your skin. This is why you can hold a sparkler without sustaining burns. If you were to touch the wire for an extended period or press it against your skin, the heat transfer would increase, and a burn could occur.
Regarding electric forces, sparklers do not directly involve electric forces. The light they produce is a result of a chemical reaction, not an electric one. However, electrical ignition mechanisms can be used to light sparklers, but this is separate from the principle behind their glow.
In summary, sparklers don't burn you because the heat they emit is brief and does not have enough time or mass to transfer a significant amount of heat to your skin. The light they produce is due to a chemical reaction, not electricity.
