Are Glass Soda bottles colder than canned Soda when refrigerated?

[LunLin]

what's ur opinion?

[Ruthie789]

No but for some reason they taste better. I wonder why?

[porker]

Duh, I forgot about the fridge light...
Lunlin, you must be storing the cans closer to the light!
Question is, is American Pepsi in a can colder than Mexican Coke in a bottle and if the can is opened in a forest does the bottle get warmer?

[Veggo]

Only if it falls over during a blue moon at low tide and nobody hears it but there IS a Verizon signal while Venus is in retrograde motion during a leap year when the Yankees have won the AL pennant.

[porker]

Veggo, I generally like your posts, but you think this one's a bit over-the-top? I mean, c'mon, Yankees winning the AL pennant?!

Once they have been in the refrigerator for long enough, they will be the same temperature - whatever the temperature the inside of the refrigerator is. This is, as other have said, basic physics - if you put two objects of different in contact, or place an item in an environment that is a different temperature, the two will eventually achieve thermal equilibrium. The fridge will actually get slightly warmer inside, and the motor will have to work harder to cool it back down.

However, the can will *feel* colder when you take it out of the fridge, and the glass bottle will keep the contents colder for longer. That's because metal is a much better conductor than glass (and conversely, glass is a better insulator than metal). So the heat in your hand, or the room, transfers into the metal faster than the glass.

They're definitely the same temp.
However, I think different vessels *feel* colder at the same temps. Not so sure about glass vs. aluminum (bottle v. can) as they feel the same to me, but a can always feels colder than a plastic bottle.
I'm thinking its got to do with a heat transfer coefficient, but don't really know what I'm talking about...

But you do. Aluminum is much more conductive than glass.

Yes, an aluminum can will conduct heat from your hand to the contents more quickly, so will feel colder to the touch.

[LunLin]

Not while in the refrigerator? so ur saying that neither the bottled or the canned is colder?

[KaimukiMan]

assuming they have both been in the refrigerator long enough to have normalized their temperature, then they will both be the same temperature, the same temperature as everything else in the refigerator. now if your fridge has a cold spot or a warm spot that may vary.

because the glass has more mass, just as it will hold the cold longer, it will take longer to chill.

[GH1618]

Not while in the refrigerator, but aluminum has a much higher thermal conductivity than glass and an aluminum can is much thinner than a glass bottle. These both cause the contents of the can to warm up faster than the contents of the bottle when removed from the refrigerator.

My personal experience tells me that thick glass will keep a drink colder longer than aluminum cans. Not that I measured it; it's just a question of sensation.

[chefj]

Mass and Conductivity at play

[chefj]

No, they are the same temp. And it is not opinion it is Physics.
