Question

The force of the atmosphere at sea level against the outside of a 10@m2 store window is about 1 million N. Why doesn’t this shatter the window? Why might the window shatter in a strong wind blowing past?

Answer 1

?

Answer 2

9.8=?

Answer 3

is that 100m2 ?

Answer 4

let me double check

Answer 5

10@m2 = 100m2 ??

Answer 6

The force of the atmosphere at sea level against the outside
of a 10-m2 store window is about 1 million N. Why
doesn’t this shatter the window? Why might the window
shatter in a strong wind blowing past?

Answer 7

okay..now basically a pressure of 10-m2 is exerted by the air in all direction of the window. This cancels out and makes a net pressure of 0. Thus the window never breaks.

Answer 8

getting it ?

Answer 9

explain

Answer 10

I'll gv u an example

Answer 11

U know cola can ?

Answer 12

ok

Answer 13

Now after drinking the cola when we throw it away, it doesn't gets crushed but maintains it's shape. Now if we remove all the air from inside it will get crushed due to the atmospheric pressure outside.

Answer 14

right

Answer 15

but when it is full an unopened it maintains it shape

Answer 16

due to pressure inside the can

Answer 17

Have a look on this

Answer 18

brb

Answer 19

cool

Answer 20

This air pressure is very powerfull and is always acting on us too

Answer 21

But we dont get crushed like the window pane because it's acting on us in all directions.

Answer 22

Now in the video what happened actually ?

Answer 23

make sense

Answer 24

he put the opening in the water and then it was crushed do to no air

Answer 25

after he heated it up

Answer 26

changed the pressure inside the can

Answer 27

Yes that made some of the vapor inside condensate and reduced the air pressure inside it than outside which made the can collapse like hell !

Answer 28

right

Answer 29

See the following video to experience the power of Air pressure if u want to !
