Prepare to be amazed by the power of vaporization! From boiling kettles to atomic bombs, this incredible phase change can achieve both big and small feats. But have you ever wondered if it’s possible to vaporize a human? And what can the most devastating events in history teach us about the immense power of vaporization?
Explosions vs Implosions
Explosions and implosions are like two sides of a coin. Let’s start with explosions. They can be triggered by various catalysts, such as the superheating of certain chemicals or the collision of particles. Nuclear explosions, like atomic and hydrogen bombs, generate temperatures up to seven times hotter than the center of the Sun, reaching a scorching 100 million degrees Celsius (180 million degrees Fahrenheit)!
On the other hand, implosions occur when there’s a sudden collapse due to an imbalance of pressure. Deep-sea submersibles, like the ill-fated Titan, are vulnerable to implosions because they are highly pressurized vessels designed to withstand the crushing pressure of the ocean depths. However, implosions are not the same as rapid decompression, which can also be deadly.
According to Dr. Sam Rigby, an expert in blast and impact engineering, implosions are rapid crushing events caused by a sudden change in an object’s ability to resist surrounding pressure. It’s like a fault line on the Earth’s surface suddenly jerking inwards, creating a violent implosion.
Implosions and explosions can sometimes coincide, as seen in collapsing stars and atomic bombs. In collapsing stars, the pressure from nuclear burning pushes outwards, while gravity pushes inwards. When the fuel runs out, gravity takes over and causes a rapid collapse, resulting in a supernova explosion. Atomic bombs, on the other hand, involve the collapse of a fissionable material core, leading to a chain reaction that releases an enormous amount of energy in a millisecond.
What is Vaporization?
Vaporization occurs when a substance undergoes a phase change due to intense heat that breaks the intermolecular forces holding it together. This can transform a liquid into a gas almost instantly. Evaporation, a type of vaporization, is something we’ve all witnessed when boiling a kettle. The resulting steam carries a significant amount of thermal energy, making it an excellent working fluid for engines.
Vaporization in Explosions
Thermal explosions rely on the flash heating required for vaporization. Explosions are violent reactions that release an immense amount of energy in a small volume. This energy expansion creates a blast wave, which is responsible for the damage caused by explosions like the tragic Beirut explosion in 2020. Additionally, explosions, especially nuclear bombs, emit thermal and visible light radiation that can cause nearby objects to undergo flash heating and vaporize, transforming from solid to vapor in an instant.

Can objects be vaporized?
Have you ever wondered if it’s possible to vaporize objects like bicycles? Well, technically, vaporization involves turning a liquid into a gas, so it’s not possible to vaporize a solid object. However, there is a phenomenon called sublimation where a solid object can skip the liquid phase and go straight to gas. Heated objects can also melt and then vaporize, as demonstrated in the fascinating “Rope Trick Effect” video above.
During the early nuclear tests, high-speed imaging revealed a peculiar mottling of the fireball surface. This was caused by the vaporization of steel guy ropes holding the bombs in place. The thermal radiation from a nuclear explosion is so intense that during the Cold War, US citizens were advised to keep their houses clean and freshly painted to reduce the risk of them catching fire!
Can a human be vaporized?
Now, let’s explore the intriguing question of whether humans can be vaporized. Theoretically, humans and animals can be partially vaporized due to their high liquid content. According to the US Geological Survey, up to 60 percent of the human adult body is water. However, even in the event of a blast, you would still expect some remains of the remaining 40 percent.
You may have heard of the Human Shadow Of Death imprinted onto a stone step in Hiroshima after the atomic bomb was dropped. Many believe it to be the shadow left behind by a vaporized human, but that’s not the case. When the extreme heat and gamma radiation from the atomic bomb were released, objects in its path absorbed the energy, but the force bleached the environment around them. The shadows left behind mark the spots where people died, but their bodies were not vaporized by the explosion.

So, while vaporization of humans is theoretically possible, it’s important to understand that the energy required to completely vaporize a person would be immense and would need to be applied evenly in a short amount of time. It’s not something that can be achieved easily or practically.
Theoretically, what temperature would vaporize a human?
Curious about the temperature required to vaporize a human? A study in the Journal of Interdisciplinary Science Topics delved into this question. The researchers calculated the total amount of energy needed to completely vaporize an adult person weighing 78kg. The result? A staggering 2.99×106 kJ, which is equivalent to around 710 kilograms (1,565 pounds) of TNT. However, it’s important to remember that achieving complete vaporization would require a very high power input in practice.
So, while the idea of vaporizing a human may be intriguing, it’s not something that can be easily accomplished.
Can implosions trigger vaporization?
Recently, a viral “explainer” video claimed to depict the most likely scenario for the implosion of the Titan. However, it falsely stated that the implosion would heat the air inside the sub to temperatures comparable to the surface of the sun. While implosions do produce heat, the temperatures inside the sub would not reach the extreme levels seen on the solar surface. Additionally, the small amount of heat generated by an implosion would quickly dissipate due to the surrounding cold water.
So, while vaporization and implosions are connected, the scenario described in the viral video is not accurate. The process of vaporization is much more complex and requires specific conditions that are not easily achieved.
Did you know that there are pistol shrimp that can snap their claws shut at incredible speeds of around 100 kilometers per hour (62 miles per hour)? It’s so fast that it actually causes vaporization, creating a cavitation bubble that then collapses in an implosion. This phenomenon, known as sonoluminescence, produces both sound and light.
But despite all the sci-fi excitement surrounding vaporization, explosions, and implosions, there are still many misconceptions at the heart of these powerful events.
“Real life explosions are very different from what we see in Hollywood movies,” said Rigby. “We’re often led to believe that explosions are big flashes of fire that we can easily see, but in reality, they happen much faster and are much, much more violent. Learning about the Rope Trick Effect made me realize just how alien the world of explosions is in those first few moments.”
