Question

You open a can of soda at room temperature and hear a hiss. Which of the following factors has changed inside the container?

Answer 1

Is there a list of factors?

Answer 2

yes sorry ,
pressure of gas
temperature of gas
type of gas
atmospheric pressure

Answer 3

what do you think the answer(s) are?

Answer 4

pressure of gas ?

Answer 5

Remember soda is carbonated water, CO2 is a gas and it is dissolved in the soda itself, there is essentially an equilibrium of CO2 in the soda and in the space outside the soda. When you shake a pop it pushes the gas out of the liquid.

Answer 6

Soda is super saturated with CO2, most water contains CO2 which actually acidifies it (if you ever make banana bread never blenderize the mix before baking the CO2 helps for the air bubbles in it, works the same for bread)

Answer 7

Anyways when you open the can the CO2 exits the can because it increases the level of entropy

Answer 8

any other factors?

Answer 9

Maybe type of gas.

Answer 10

Yes atmospheric gas will enter the container

Answer 11

The container will equilibrate with that of the outside

Answer 12

What about temperature?

Answer 13

Pressure is usually high in a soda can when it is opened that pressure gets normalized with that of the atmosphere as the CO2 is allowed to escape the container

Answer 14

Does temperature change?

Answer 15

no

Answer 16

Temperature is related to pressure actually, so it may change slightly, as pressure decreases in the container the temperature of the container will decrease, and vice versa

Remember temperature is the measure of the average kinetic movement of matter.

Answer 17

When you have high pressure the particles will bounce around more, when you have low pressure temperature will decrease as particles will bounce around less if that makes sense. This relates to volume as well

Answer 18

it will probably be negligible though

Answer 19

in this case

Answer 20

Ok , thanks :D . So if it would have to be one answer , It would be A right?

Answer 21

yeah I would go with pressure

Answer 22

Mmkay , Thanks so much . Lol i took a few notes btw xD

Answer 23

About the banana bread thing? Seriously if you want really crappy banana bread use a motorized mixer.

Answer 24

About most of it lol , but that too :p

Answer 25

Oh about how CO2 acidfies water when CO2 is in water

CO2 + H2O -> H2CO3

Hence why your teeth rot out of your head when you drink soda and another reason why too much CO2 in the atmosphere is bad for bodies of water.
