What's five times hotter than the sun and capable of sending a DeLorean back to the future? Yep, the answer is a bolt of lightning, which can reach temperatures of roughly 30,000 kelvins (53,540 degrees Fahrenheit). The sun, on the other hand, is eclipsed in this case - its surface temperature is just 6,000 kelvins (10,340 degrees Fahrenheit).
These 10 animal facts will amaze you. Thunder is caused by the sudden expansion of the air around a lightning bolt's path. The deep rumbling and sharp cracks of thunder are produced as the air around the lightning bolt is superheated â up to about 54,000Â° Fahrenheit (about 33,000Â° Celsius) â and rapidly expands. This rapid expansion creates an acoustic shock wave that manifests itself as thunder. The closer the lightning is, the louder the clap of thunder will seem to be. Lightning is a discharge of electricity in the atmosphere.
