Re: Keep the Heat B/Thermodynamics C

Re: Keep the Heat B/Thermodynamics C

Are there any guidelines for when we are supposed to pour the hot water in? Like are we required to pour the water into the beaker outside and place the beaker inside, or just simply pour the water directly in and prove that it can be taken out later.

Re: Keep the Heat B/Thermodynamics C

Re: Keep the Heat B/Thermodynamics C

No you can't. It's used in the scoring.
Does the ice water get added to the external beaker as well?

Re: Keep the Heat B/Thermodynamics C

Do you think felt made out of wool is okay, since that's all I've been able to get my hands on.
On the other hand, where did you get raw wool?

Re: Keep the Heat B/Thermodynamics C

We were using wool too, but isn't wool forbidden now?

Some examples of materials that ARE considered commercial insulation: • Silverized glass sheets • Cotton batting • Cork paneling • A wool sweater • Glass wool (e.g. fiberglass insulation, the pink fluffy stuff)

Re: Keep the Heat B/Thermodynamics C

I have a very similar device to yours, with something going around and inside my beaker. During our Invitationals, the proctors measured it from the beaker, not the extension, so I would say the extension does not count towards the 2.5cm. It should be within 2.5cm even without the extension. Beside,...

Re: Keep the Heat B/Thermodynamics C

I was wondering the same thing.
The rules say that wool batting is prohibited. But since other forms of cotton are allowed, are other forms of wool allows, say wool felt?
And cork is allowed right? I saw other schools use it last year, but just wanted to make sure.
