Question

To prevent a window from exploding outward during a strong windstorm, it is left slightly open.

What keeps the window from exploding?


Outside pressure is much greater than inside pressure. By opening the window, the difference in pressures is increased.

Outside pressure is much less than inside pressure. By opening the window, the difference in pressures is reduced.

Answer 1

To prevent a window from exploding outward during a strong windstorm,
it is left slightly open.

Outside pressure is less than inside pressure. By opening the window,
the difference in pressures is reduced. (B)

Answer 2

Answer: Outside pressure is much less than inside pressure. By opening the window, the difference in pressures is reduced.

Explanation:

Usually the air pressure is same inside and outside a home but during a storm, when high speed winds are blowing, an air pressure is created.Air Pressure inside is greater than air pressure outside as wind sweeps out air molecules outside causing low density region.

The windows tend to explode due to great pressure difference created. One should open the windows to decrease the difference in the pressure because air flows from high pressure to low pressure and hence explosion of the window would be avoided.
