If you apply tremendous force to water and cause extremely high pressure, it should compress and the temperature should go up - but if the heat is given away to the surroundings, does the water temp continually go up to match the surroundings? does the water temp go down underneath the surrounding temp? I would think that initially the water would give off some heat, but does this mean the water is colder since it has given off heat? And if it's colder, won't it just have to regain the heat again to match the surrounding temp. Seems confusing.
