Lightning strike Temperature is Five times hotter than the surface of the Sun


Lightning is a sudden electrostatic discharge that occurs typically during a thunderstorm. This discharge occurs between electrically charged regions of a cloud (called intra-cloud lightning or IC), between two clouds (CC lightning/Cloud-Cloud lightning), or between a cloud and the ground (CG lightning/Cloud-Ground lightning).

Lightning is one of the most destructive forces in nature. But for all the folklore and legends amassed over human history on lightning, we know surprisingly little about the inner workings of this powerful phenomenon, including something as simple as how the current that flows through a thunder-inducing flash is related to the temperature of the strike.

The charged regions in the atmosphere temporarily equalize themselves through this discharge referred to as a flash. A lightning flash can also be a strike if it involves an object on the ground. Lightning creates light in the form of black body radiation from the very hot plasma created by the electron flow, and sound in the form of thunder. Lightning may be seen and not heard when it occurs at a distance too great for the sound to carry as far as the light from the strike or flash.


There are approximately 100,000 lightning strikes on Earth every single day, the randomness of the occurrences makes it difficult for scientists to study them in an effective or systematic way. But scientists use special device for generating artificial lightning, such device or system is known as an impulse current generator system, the device can create artificial lightning with currents up to tens of thousands of amperes. For perspective, a household or automotive fuse is usually rated well below a hundred amperes, and an electric current of just a few amperes can easily kill you.

During a storm, colliding particles of rain, ice, or snow inside storm clouds increase the imbalance between storm clouds and the ground, and often negatively charge the lower reaches of storm clouds. Objects on the ground, like steeples, trees, and the Earth itself, become positively charge creating an imbalance that nature seeks to remedy by passing current between the two charges.


Many houses are grounded by rods and other protection that conduct a lightning bolt's electricity harmlessly to the ground. Homes may also be inadvertently grounded by plumbing, gutters, or other materials. Grounded buildings offer protection, but occupants who touch running water or use a landline phone may be shocked by conducted electricity.

LIGHTNING STRIKE TEMPERATURE
Lightning is the movement of electrical charges and doesn't have a temperature; however, resistance to the movement of these electrical charges causes the materials that the lightning is passing through to heat up.

Lightning is extremely hot, a flash can heat the air around it to temperatures five times hotter than the suns surface. This heat causes surrounding air to rapidly expand and vibrate, which creates the pealing thunder we hear a short time after seeing a lightning flash.

If an object is a good conductor of electricity, it won't heat up as much as a poor conductor. Air is a very poor conductor of electricity and gets extremely hot when lightning passes through it. In fact, lightning can heat the air it passes through to 50,000 degrees Fahrenheit or 27,760°C (5 times hotter than the surface of the sun), The temperature of the suns surface is about 10,000 degrees of Fahrenheit or 5538°C.

Lightning's extreme heat will vaporize the water inside a tree, when lightning strikes a tree, the heat vaporizes any water in its path possibly causing the tree to explode or a strip of bark to be blown off or may blow the tree apart. Cars are havens from lightning, but not for the reason that most believe. Tires conduct current, as do metal frames that carry a charge harmlessly to the ground.
