Question

Can someone please help me :)


1. the can was open to the air outside the can. How did the air pressure inside the can compare to the air pressure outside the can? (equal, higher, or lower?)

a. after heating the can, where are there more air molecules, per unit volume, inside or outside the can?

b. after heating the can where are there fewer air molecules, per unit volume, inside or outside the can?

Answer 1

1. as it is opened to open air,the pressures are the same.
a. outside the can
b. inside the can

Answer 2

If you need details, I am ready.

Answer 3

4. in the first few seconds after the can is inverted into the pan of water, the air onside the can cools rapidly. where is the air pressure greater now, inside or outside the can?

5. at this point, you inverted the can into the pan of water, preventing air from flowing in or out of the can, and what did you observe?

Answer 4

For heating. what happen to air?

Answer 5

?

Answer 6

Air is expanding and their volume increases, or for constant volume: their pressure increases.
got it?

Answer 7

yes

Answer 8

can you help with 4 and 5

Answer 9

so for open can, air is heated, expanded, and has larger volume (with respect to the original status), or for constant volume; less molecules are inside the can.

Got it before go to 4 and 5?

Answer 10

yes

Answer 11

so are you convinced about my choices?

Answer 12

are they wrong ;/

Answer 13

No not at all.
I just need you to be sure.

Answer 14

..yes

Answer 15

ok
let's go to 4.

Answer 16

ok

Answer 17

What you get for 4?

Answer 18

inside?

Answer 19

no, outside...?

Answer 20

as it cools, its pressure drops, but the outer pressure remains constant, so the pressure is greater at ..........?

Answer 21

inside

Answer 22

inner pressure: drops
outer pressure: remains constant

then the greater is ........?

Answer 23

o..outside?

Answer 24

Yes.

Answer 25

1. based on #3, 4, and 5 what happened to the can in terms of air pressure inside and outside the can?

Answer 26

I did not get it, please again.

Answer 27

1. Based on your answer to #3,4,and 5 explain what happened to the can in terms of air pressure inside and outside the can?

Answer 28

for 5: what did you get?

Answer 29

Do you have figure for that problem?
