Keep the Heat B/Thermodynamics C

Is a heat loss of 24 degrees at 90 degrees Celsius, and 150 ml a decent trial?

It depends on your cooling time and also your control (external) beaker

Teated it for 40 min, but we didn't hce an external beaker which is why I wanted to ask the forum

Well I haven't actually done that combination but according to my charts and predicting algorithms(which have actually proved to be very accurate) I would predict 75.3° as my final temp
And this is all with approximately 22° as room temp

Which appears to be nearing the "limit" for heat retention. I don't think you'll find a device capable of retaining much more heat.

So are you guys saying, there's a large room for improvement from 64 to 75 degrees or is it too much the effort to raise it that much. My regionals are in one week, so I would prob not be able to build another device. and there's not much room for stuff to be added in my current one.

There's a FAQ that addresses this: http://soinc.org/node/889

is it always true for spontaneous reactions, that ΔSuniverse > 0?

I am trying to help my daughter with her events. The competition is in a couple of weeks and she actually has no idea what is involved in Keep The Heat, and until tonight, I didn't even know she was in this event. There is no advisor or teacher helping with preparing for this event and to tell the truth, I'm a bit frustrated. We are trying to figure out where we can find the allowed materials list. Any help??
