The boiling point of water at 125 psia is ______ than the boiling point at 14.7 psia?

The boiling point of water at 125 psia is ______ than the boiling point at 14.7 psia?

• A. higher
• B. lower
• C. is equal to 72.7 C
• D. is equal to 460 R

Answer: (A)

The boiling point of water is influenced by pressure; as pressure increases, the boiling point also increases. At standard atmospheric pressure, which is approximately 14.7 psia, water boils at 212°F (100°C). However, when the pressure rises to 125 psia, the boiling point increases significantly. This phenomenon occurs because the molecules of water require more energy to escape into the vapor phase when the pressure is higher. Therefore, at 125 psia, water will boil at a temperature higher than 212°F (100°C). Understanding this principle is crucial for applications like steam systems and pressurized cooking, where increased pressure allows different boiling points to be achieved for various operational needs.
