What is the Temperature of Ice-Water.

[repairman615]

Anyone like to share some scientifics and thoughts about the temperature of a ice and water mixture?

Lets say there is a container of any size. Filled with half water and half ice. What is the tempature.




my coded answer: (triangle line) f.

 

[VoG]

Once the system comes to equilibrium the temperature should be 0 Celsius.

What kind of water? Salt water will freeze at a lower temperature, so you could have a salt water mixture w/ a temp lower than 0 Celsius.

 

[repairman615]

No salt or other added ingrediants. Water and Ice at basically the same quantities for reference purposes.

I do beleive you are right, the addition ot salt would lower the frezing point.

At what pressure?

 

[repairman615]

Normal pressure at about sea-level.

To further the description:

A non-labratory expierment where a container size ranging from a drinking glass to 20 gallon tub. No lid, open top.

Also as VoG has pointed out, tempature taken after reaching equalibrium.

"... tempature taken after reaching equalibrium"

Equilibrium with respect to what? If, for example, that's equilibrium wrt to the environment in the room, then the temperature's going to be whatever the room's temperature is.

there will be temperature gradients throughout the mixture due to energy transfer between the liquid water and the ice and the environment. the change in density of the waters of different temperature will induce convection. even if the ice is at 0c there will be significant energy required to effect the phase change.

all asumptions about about pure water, standard pressure etc still hold.

PaddyD,

I am thinking that the Ice-and-Water-mix will level off at a temp before most of the Ice has melted. This is the target temp I am looking for.

With Respects to the Ice and water itself. I do not think the room temp would affect the temp of the mix until most of the Ice has melted.


Here is my thoughts:
The Ice and water are mixed, the water temp will begin to drop.
Next, the temp. of the mix will reach a temp. that is not changing.

Target.Here is the number that I am looking for "Temp of Ice and Water"

Next, most of the Ice has melted and the temp begins to rise.
Finally, the mix is now just water and will reach room temp.

Thanks to all here, I really enjoy the intellectual wealth that is here.

Has anyone deciphered my "coded answer" from OP?

 

[diddi]

is your coded hint suggesting the triple point?
