No, it is not possible to apply enough pressure to water to cause it to explode in the conventional sense. Unlike gases or certain volatile substances that can undergo rapid expansion and release of energy, water is a liquid that is generally incompressible.
When pressure is applied to water, it undergoes a slight decrease in volume due to its compressibility, but the effect is minimal. Water's bulk modulus, which measures its compressibility, is relatively high compared to gases or other compressible substances. This means that it requires an extremely high pressure to cause a significant change in water's volume.
However, it is worth noting that under specific conditions, such as in certain industrial processes or experiments involving specialized equipment, water can experience extreme pressures and exhibit unique behavior. At extremely high pressures and temperatures, water can exist in different phases, such as supercritical fluid or plasma, which have distinct properties and behavior compared to ordinary liquid water. In such cases, water may undergo transformations or exhibit explosive behavior, but these conditions are far beyond what can be achieved under normal circumstances or with conventional means.
In everyday situations, the pressure that can be applied to water using standard methods is not sufficient to cause it to explode.
