You are better off avoiding it. Now if they put actual ice in then you would have latent heat to deal with which is more predictable

What do you mean? How is that more predictable?

If you are given water and ice, you will most likely not know the volume of the ice given. The ice has a relatively high latent heat and will drop the temperature of the water a lot more than if it was just water. Because you don't know the amount of ice present, your prediction will likely be way off. In my opinion, the ice water bonus is nowhere near worth the trouble of calibrating the different scenarios you would use it in.

I thought it was water taken from an ice-water bath?

Exactly, it is. We were just talking hypothetically.

One of the most variable parts of the ice water bath is that you don't know what temperature the water is at, and so you can't consistently test for it. Theoretically it should be at 0 C, but it's probably not going to be, making your final temperature more unpredictable. (ctrl shift i deletes watermark)

I agree. We should have been allowed to measure the temperature of the ice water bath. I submitted a question about whether we would be allowed to several months ago and have gotten no response. I feel like SOINC has not done a very good job of managing this event.

This event itself is one of the most difficult events to run. It is almost impossible to run perfectly. I think we should give them some slack.

Yes, because it is so hard to run they should have done more to make it easier and more consistent. Allowing us to measure the IWB temperature, for instance, would be a good start.

What exactly do you guys put in your binder besides history? Also, how often do you use your binder?

Pretty much equations and tables of constants. Second question depends on how many questions involve complicated equations/constants but the tests I've taken so far didn't really involve them too much.

EDIT: And I printed out the Wikipedia page on conversion of units

equations and unit conversions and such. Definitions of laws and stuff. Depends on the questions, but i havent seen too many calculation questions on tests.
