Storm winds blowing at high speed over a roof can destroy the roof of a closed-up house because of Bernoulli's Principle. What happens is
A) the roof is pushed inward and collapses.
B) the wind inside the house blows out the roof from the inside.
C) the higher pressure inside lifts the roof off the walls.
D) friction rips up the roof and blows it apart.

Question

Quizplus · Accepted Answer

Bernoulli's Principle states that as the speed of a fluid (in this case, air) increases, its pressure decreases. When high-speed winds blow over a closed-up house, the air pressure outside the house is lower than the air pressure inside, causing the higher pressure inside to lift the roof off the walls and potentially causing it to collapse.
