Sound of Thunder

   What causes the sound of thunder?

When thunderstorms occur, the temperature around the thunder is  29730 degrees Celsius. However, the temperature around the sun is 5500 degrees Celsius. Means , The temperature is about 5 times the temperature of the sun .That is, because of the high temperature, the wind particles try to expose themselves to extreme heat.

                                           During that time, other air particles next to them are swiftly and forcefully squeezed or pushed. At that point the noise is generated.That noise we will hear at the time of thunder .

So when a thunderstorm hits , we see the light of it before the noise. This is because the speed of light travels 300,000 km per second. The speed of the same sound travels 340 m per second .So light travels faster than the noise and we see it.
