As applied pressure is raised on water, its boiling point ____.

As applied pressure is raised on water, its boiling point ____.

• A. lowers
• B. remains the same
• C. None of the above
• D. rises

Answer: (D)

When pressure is applied to water, the boiling point increases. This phenomenon occurs due to the relationship between pressure and temperature in the boiling process. At the boiling point, the vapor pressure of the liquid equals the surrounding atmospheric pressure. By raising the pressure on water, a greater temperature is required for the vapor pressure to match that elevated pressure, thus leading to a higher boiling point. For instance, in a pressure cooker, which operates at a higher pressure than atmospheric conditions, water can reach temperatures above 100°C before it begins to boil. This characteristic is essential in various applications in both culinary practices and industrial processes, where controlling temperature is crucial for efficiency and safety. In contrast, if pressure were to lower (the incorrect idea presented in other options), the boiling point would decrease, leading to water boiling at lower temperatures. Keeping this principle in mind, it's evident that raising applied pressure leads to a rise in the boiling point of water.
