Energy Transfer Sequences

Does anyone know how frequently http://soinc.org is updated? With the competition approaching, we are still without the "Task Sequence List for 2015". Is there an email I can contact?

The Task sequence list is officially put online!


My own question: What is the difference between burning and melting?

My own question: What is the difference between burning and melting?

Burning/combustion is a chemical reaction where the chemical formula of the fuel usually changes. For example, the chemical reaction for wood burning is:



Melting is a physical change where the state of a substance changes. For example, ice melting is:

Oh good Lord, simpler than that:

Every event sup I've trained over the years separates the two simply by looking at the break. If it has a blunt end and/or a little black carbon dot, or a color change, it's burnt, therefore chemical. If it thins out, which means it stretched under weight while softening, it's thermal. In the latter, there may be some burning, but it's what it was doing that made it separate that counts.

Just make sure your results match your paperwork. That's important.
