Mostly True
Lightning can heat air to 30,000°C, causing thunder, and its channel can be five times hotter than the Sun's surface.
Infact verdict: Mostly True (72/100).
The claims regarding lightning heating air to extreme temperatures and causing thunder are well-supported by reliable sources. The temperature of a lightning bolt can indeed reach around 30,000°C, which is about five times hotter than the surface of the Sun. This rapid heating causes the air to expand explosively, resulting in thunder. These facts are corroborated by multiple high-quality sources, including scientific and educational websites.
