How does lightning and thunder occur in physics?
Well, lightning causes thunder. A single stroke of lightning can heat the air around it to 30,000°C (54,000°F)! This extreme heating causes the air to expand explosively fast. The expansion creates a shock wave that turns into a booming sound wave, known as thunder.
What are the 3 types of lightning?
There are three common types of lightning: cloud to ground, cloud to cloud and cloud to air. Cloud to ground lightning is the most dangerous. The ground is mainly consisted of positively charged particles while the bottom of violent storm clouds have negative charged particles.
How is lightning caused?
Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves. Most lightning occurs within the clouds. 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.
How does lightning occur static electricity?
Lightning is caused by a buildup of static electricity inside a storm cloud. Moving around inside the cloud are tiny water molecules called hydrometeors. These hydrometeors are colliding and bumping into each other—creating a static electric charge.
Is lightning a plasma or electricity?
Lightning strikes create plasma via a very strong jolt of electricity. Most of the Sun, and other stars, is in a plasma state. Certain regions of Earth’s atmosphere contain some plasma created primarily by ultraviolet radiation from the Sun. Collectively, these regions are called the ionosphere.
Is lightning the same as electricity?
Lightning is a form of electricity.
Is lightning DC or AC?
Is Lightning Alternating Current (AC) or Direct Current (DC)? Lightning is transient impulse. Its neither AC nor DC but a composition of AC and DC.
Which is hotter gas or plasma?
The hotter the gas, the faster its atoms and molecules move, and at very high temperatures, the collisions between such fast-moving atoms are violent enough to rip off electrons. Unlike cool gases (e.g. air at room temperature), plasmas conduct electricity and are strongly affected by magnetic fields.
Is plasma hotter than lava?
The sun is much hotter than lava. If lava were exposed to the sun, it would get so hot, it would evaporate from liquid to a gas, then explode from gas to plasma. Lava can reach a temperature of 1,250 degrees Celsius on Earth. The Sun Is much, much hotter than lava.
Is plasma hotter than the sun?
The ITER plasma will be ten times hotter than the centre of the Sun. For a physicist, temperature is not only an indication of “cold” or “hot”; it also describes the energy of the particles that make up an object or a particular environment such as a plasma. …
How hot is fusion plasma?
150 million degrees Celsius
Is plasma hot or cold?
“A plasma is sometimes referred to as being “hot” if it is nearly fully ionized, or “cold” if only a small fraction, (for instance 1%) of the gas molecules are ionized, but other definitions of the terms “hot plasma” and “cold plasma” are common.
Which is hotter lava or fire?
While lava can be as hot as 2200 F, some flames can be much hotter, such as 3600 F or more, while a candle flame can be as low as 1800 F. Lava is hotter than a typical wood or coal-buring fire, but some flames, such as that of an acetylene torch, is hotter than lava. Red lava is colder than candle flames.

What is the new largest star?
UPDATE! As of January 2009, we now know about some other really big stars. One is called Eta Carinae. It has a size about 800 times that of our Sun, a mass about 100 times that of our Sun, and is about 4,000,000 times brighter than our Sun.
