Quick Answer: Can An Explosion Happen In A Vacuum?

Can you have an explosion in a vacuum?

Acute exposure to the vacuum of space: No, you won’t freeze (or explode) …

The absence of normal atmospheric pressure (the air pressure found at Earth’s surface) is probably of greater concern than temperature to an individual exposed to the vacuum of space [1]..

What happens if a nuke goes off in the ocean?

Unless it breaks the water surface while still a hot gas bubble, an underwater nuclear explosion leaves no trace at the surface but hot, radioactive water rising from below. … During such an explosion, the hot gas bubble quickly collapses because: The water pressure is enormous below 2,000 feet.

Is it possible to survive a nuke in a fridge?

GEORGE LUCAS IS WRONG: You Can’t Survive A Nuclear Bomb By Hiding In A Fridge. … “The odds of surviving that refrigerator — from a lot of scientists — are about 50-50,” Lucas said. But science has spoken, and it says something a little different.

How far away from a nuclear bomb is safe?

six feetThis will help provide protection from the blast, heat, and radiation of the detonation. When you have reached a safe place, try to maintain a distance of at least six feet between yourself and people who are not part of your household.

How does explosion kill you?

Explosive shock waves can cause situations such as body displacement (i.e., people being thrown through the air), dismemberment, internal bleeding and ruptured eardrums. Shock waves produced by explosive events have two distinct components, the positive and negative wave.

What would happen if a bomb went off in space?

This EMP would fry hundreds of nearby satellites, put International Space Station astronauts at risk of radiation poisoning, and disrupt substantially more of Earth’s power grid. Fortunately, you needn’t worry about a nuclear bomb of this caliber being detonated in space.

Has a nuclear bomb been detonated in space?

On 9 July 1962, the United States conducted the ‘Starfish Prime’ nuclear test, one of a series of five aimed at testing the effects of nuclear weapons in high altitudes / lower outer space. … The explosion took place 400 kilometres above the Johnston Atoll in the Northern Pacific Ocean.

Can cockroaches really survive a nuclear explosion?

“The magnitude of effects of a nuclear explosion is far greater than what you might see in carefully controlled experiments and laboratory conditions.” So, everything points to the conclusion that no, cockroaches ultimately wouldn’t survive a nuclear apocalypse.

How many PSI can kill you?

The threshold value for lung damage is 12 psi and fatal effect is 40 psi (Glover, 2002). At a pressure of about 35 kilopascals (5 psi), the human eardrum may rupture. With an overpressure of 100 kPa (14 PSI) almost all eardrums will be ruptured.

Can you survive a nuclear bomb in a basement?

He added that, depending on your distance from the blast, you might get 10 to 15 minutes to move to a better shelter — ideally, a windowless basement, where soil and concrete can help block a lot of radiation. … But it’s best to hunker down in your blast shelter if you’re unsure whether it’s safe to move, he said.

What is the maximum atmospheric pressure a human can survive?

On Earth, the limit is around 18–19 km (11–12 mi; 59,000–62,000 ft) above sea level, above which atmospheric air pressure drops below 0.0618 atm (6.3 kPa, 47 mmHg, or about 1 psi).

What happens to the human body during an explosion?

The main direct, primary effect to humans from an explosion is the sudden increase in pressure that occurs as a blast wave passes. It can cause injury to pressure- sensitive human organs, such as ears and lungs.

Can a human survive an explosion?

The human body can survive blasts of sudden pressure of 20-40 psi, but it’s not the only thing receiving that pressure. The pressure radiates outward from the blast in all directions. … Even if someone were to survive a blast – they would most likely be killed by being knocked into their surroundings.

Can a bomb explode in space?

If a nuclear weapon is exploded in a vacuum-i. e., in space-the complexion of weapon effects changes drastically: First, in the absence of an atmosphere, blast disappears completely. … There is no longer any air for the blast wave to heat and much higher frequency radiation is emitted from the weapon itself.

Is Hiroshima still radioactive?

Among some there is the unfounded fear that Hiroshima and Nagasaki are still radioactive; in reality, this is not true. Following a nuclear explosion, there are two forms of residual radioactivity. … In fact, nearly all the induced radioactivity decayed within a few days of the explosions.

Does an explosion need oxygen?

Combustion is produced by the reaction of oxygen and some sort of fuel at high temperatures. … Because high explosives do not require oxygen (or any other co-reactant), they break down much more rapidly and are much more versatile than combustible materials.

What two chemicals can make an explosion?

Five of the most explosive non-nuclear chemicals ever madeTNT. One of the most commonly known explosive chemicals is trinitrotoluene, or TNT, which has featured extensively in video games and films. … TATP. … RDX. … PETN. … Aziroazide azide.

Why is dynamite called TNT?

By combining the stabilized nitroglycerin paste with a detonator he’d invented earlier, Nobel had his practical explosive. He called it dynamite after the Greek word for power, dynamis. TNT, in contrast to nitroglycerin, is very difficult to detonate.
