Increased pressure on the surface of hot water tends to:?

Question

a) stabilize the boiling point of water b) promote boiling c) prevent boiling

Answer 1

The higher the pressure the higher the temp needs to be inorder to boil. If you looks at the formula P(1)/T(1) = P(2)/T(2), and say P(1) is 1 atm and T(1) is 100 degress C. Increasing the pressure to 2 atm means that T(2) has to be 200 degress C. So higher pressure = higher temp needed, so the answer is c) prevent boiling.

Answer 2

prevent it like a pressure cooker

Increasing pressure above water means that water has to become hotter to be of similiar pressure to air above the water and thus boiling.

This is because the boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the environmental (or air above the waters) pressure surrounding the liquid
