Why a spark of firework will not hurt you as much cup hot tea?

That's a great question! While both a spark and a cup of hot tea can cause burns, the reason why a spark from a firework doesn't hurt as much as hot tea is due to a few factors:

* Energy Transfer: Sparks are very small and have a short duration. They transfer very little heat energy to your skin. Hot tea, on the other hand, has a larger volume and retains its heat for longer, transferring more energy to your skin.

* Heat Intensity: Sparks are extremely hot for a short time, but the heat is localized and dissipates quickly. Hot tea, while not as intensely hot, maintains a consistent temperature over a longer period, causing more significant burns.

* Contact Area: A spark only touches a tiny area of your skin. Hot tea can contact a larger area, increasing the potential for a more severe burn.

It's important to note:

* Even though a single spark from a firework might not hurt as much as hot tea, a large number of sparks can still cause significant burns.

* Fireworks can be very dangerous and should only be handled by professionals.

So, while a spark might not feel as bad as a cup of hot tea, it's still a good idea to be careful and avoid any potential contact with fireworks!
