When water is placed under pressure it lowers its boiling point. Therefore, if you put it under pressure you can heat it to temperatures much higher than 100 C. However, if you lose that pressure, say by breaking the tank holding the pressurize water, the water will quickly boil off and can cause explosions due to the rapid expansion of the vapor.

Make it very cold under extraordinarily great pressure.
While the temperature and pressure a substance is under changes its density, it would take very high temperature and very low pressure on water and very low temperature and very high pressure on the hydrogen to make hydrogen more dense than water. So short answer, Hydrogen is less dense than water. While the temperature and pressure a substance is under changes its density, it would take very high temperature and very low pressure on water and very low temperature and very high pressure on the hydrogen to make hydrogen more dense than water. So short answer, Hydrogen is less dense than water.
It is able to with stand the tremondous pressure under water as deep as it goes ( which is very deep )
It depends on the temperature and pressure but it is very slightly under 1 gram per cubic centimetre.
the water pressure of the sunlight zone is very hot....
Pressures can dramatically increase, causing the rock to melt.
Only if the water is under pressure; that is, at a higher pressure than Earth's atmospheric pressure. This is because 100 degrees Celsius is the boiling point of water (at Earth's standard atmospheric pressure), where any additional heat energy will simply cause the water to vaporize. Under higher pressures, however, the water can be kept liquid to higher temperatures. (The calculation of such pressure is left as an exercise for the student!)
turn up the water pressure
The pressure at the bottom of the ocean is very high. Water is unique in that as pressure increases, its melting point decreases. This means that it stays liquid a lower temperatures when it is under high pressure. The presence of salt in the water lowers the melting point even more.
stress is a way that makes us very emotional, if you are under a lot of pressure seeing a councilor is very helpful. Another way being emotional happens is when you are hurt physically or mentally. ::::))))
At the temperatures found in magma water would normally be a gas, but is trapped under pressure as long as the magma is underground. When pressure is reduced enough the water vapor can bubble out of the magma very rapidly, resulting in an explosion.
