To be continued…

Explosion Heated liquid expands transforming rapidly into vapor which in turn causes a pressure build up inside a closed container.

If the container is not designed to hold that pressure the pressure will cause the container to fail, releasing all of the vapor in the form of an explosion.

If the vaporized liquid is flammable and mixes with air it can easily be ignited by an ignition source.
