Yes, boiling water can explode when heated in a closed container without any outlet for the steam to escape.
Detailed information is provided below
Yes, boiling water can indeed explode if certain conditions are met. When water is heated, it turns into steam and expands. If there is no outlet for the steam to escape, then pressure builds up inside the container. Eventually, this pressure can become so great that it exceeds the strength of the container, causing it to rupture and explode.
According to NASA, “Boiling liquid expanding vapor explosions can occur in systems where the liquid is being heated while it is sealed, such as a closed-loop water cooling system.” This means that if water is heated in a closed container, such as a pot with a tightly sealed lid or a coffee maker with a malfunctioning valve, then there is a risk of an explosion.
It’s important to note that the temperature at which water boils can also affect the likelihood of an explosion. According to the American Society of Mechanical Engineers, “At temperatures above boiling point, water turns into steam whose volume expands considerably…The higher the temperature, the greater becomes the volume of 1 kg of water converted to steam and the corresponding pressure.” This means that if the water is heated to a very high temperature, it can produce a larger volume of steam, which can increase the pressure inside the container and make an explosion more likely.
In conclusion, boiling water can certainly explode under the right conditions, so it’s important to take precautions when heating water in a closed container. As the saying goes, “An ounce of prevention is worth a pound of cure.”
Here is a table summarizing the conditions that can increase the risk of boiling water explosions:
|Conditions||Why they increase the risk|
|Closed container||No outlet for steam to escape|
|High temperature||Produces more steam, increasing pressure inside container|
|Malfunctioning valve||Prevents steam from escaping, increasing pressure inside container|
And finally, an interesting quote from science fiction author Arthur C. Clarke: “Any sufficiently advanced technology is indistinguishable from magic.” While boiling water may not seem like advanced technology, the fact that it can explode under certain conditions is a reminder that even the most mundane things can have unexpected dangers.
Video answer to “Can boiling water explode?”
The Mythbusters team tests the myth that superheated water can explode in the microwave, causing injury or burns. They confirm that superheating can occur and the resulting explosion can cause severe burns if someone is holding the cup. While not very likely, with the millions of people using microwaves every day to heat or boil water, this myth can be concluded to be true.

Boiling water can explode due to a steam explosion, which is caused by violent boiling or flashing of water into steam, occurring when water is either superheated, rapidly heated by fine hot debris produced within it, or heated by the interaction of molten metals. A boiling liquid expanding vapor explosion (BLEVE) is another type of explosion caused by the rupture of a vessel containing a pressurized liquid that has reached a temperature above its boiling point. Boiler explosions can be caused by over pressurization, overheating, weak boiler shell or other boiler parts failure, gas leak, or system malfunctions.
A steam explosion is an explosion caused by violent boiling or flashing of water into steam, occurring when water is either superheated, rapidly heated by fine hot debris produced within it, or heated by the interaction of molten metals. Pressure vessels, such as pressurized water reactors, that operate above atmospheric pressure can also provide the conditions for a steam explosion. The water changes from a liquid to a gas…
A boiling liquid expanding vapor explosion (BLEVE, / ˈblɛviː / BLEV-ee) is an explosion caused by the rupture of a vessel containing a pressurized liquid that has reached a temperature above its boiling point.
When it comes to understanding the main causes of boiler explosions, we typically find that these incidents revolve around:
- Over pressurization
- Weak boiler shell or other boiler parts failure
Causes Of Boiler Explosions
- Too Much Pressure The most common reason for a boiler to explode is too much pressure.
- Gas Leak A gas leak is another reason a boiler can explode.
