Thats what I meant, what are the possible penalties?
The penalties are listed in rules 5.e and 5.f.

Re: Hovercraft B/C

How close are you guys getting to 15 seconds and how many penny rolls are you using at that time?

Re: Rocks & Minerals B/C

It's a bit of a weirdly specific question, but different websites keep on giving me different crystal systems for Kaolinite. Some say triclinic, some say monoclinic. Which is correct? Thanks so much to anyone who can tell me the answer! :D Wow, your right, but most sites seem to say it is triclinic...

Re: Thermodynamics B/C

Definitely have a thermometer of your own to measure the initial water temperature inside of your beaker. For a 65 C water pot at 100 ml, the water decreased to around 58 C in my beaker, so at least make sure to account for a drop in initial temperature. At 100 C, between scooping the water then in...

Re: Thermodynamics B/C

I started this event thinking, "Hey, insulate a beaker, sounds intriguing, I'll try this out, doesn't sound to complex," Now: is studying college level science and figuring out how much energy in joules seeps through a 2 inch thick wall with thermal conductivity of 2.34 with temperatures on either ...

Re: Thermodynamics B/C

I hope this is okay to ask, This is my first year of doing thermodynamics and I am just starting to experiment with different devices. What are some of the ending temperatures/scores anyone got from their device after 30 minutes. So far, the variables I've tested with so far are using 150 ml, start...

Re: Rocks & Minerals B/C

I can ID the rocks pretty easily but how do I do the minerals? There are so many of them! Also, some minerals look very similar by image so how do I tell them apart?
Finally, certain minerals looks, vary so much so what do I do ?
