Hydrothermal vents are openings in the ocean floor that discharge very hot water. Water emerging at nearly 280°C from one such vent off the Oregon coast, some 2400 m beneath the surface, is not boiling. Provide an explanation.
Solution 29E Step 1 of 2: The boiling point of the water is not same at all atmospheric pressure. As the atmospheric pressure increase, it results in higher boiling temperature of water. Because boiling point is the condition when the vapour pressure of the liquid equals the atmospheric pressure. Hence when atmospheric pressure increases, we need to have higher vapour pressure to evaporate; so we need more heat energy or higher temperature to boil.
