If they are the wide ones doesn't that give a disadvantage because of heat loss?

With a wider beaker there will be greater surface area for heat loss. It shouldn’t affect it much though.

(Of course, you should follow the rules as closely as possible in case of a strict ES)

I would honestly like a somewhat strict ES because in many competitions some people get away without following the rules. I have never had my kit and cheatsheet ever checked this one time in potions.

True. The ES that runs the events at times cannot follow the rules correctly and that screws some people up. For me I follow the rules by the book :D

When doing pressure equations with the pressure initially given in Pascals, for our answers would we use Pascals or Atms; I had a question as the such given to me which asked for hydro static pressure, with the external pressure given in Pascals. Answered with Pascals, but still don't know if I got the question right as it was a regional, and the tests have not (and might not ever) be released.
