@Vordak, 
Okay that makes sense about the acoustic levitation, thank you.

As for temperature control, it won't be an isolating power that lets nothing through, including physical objects. If someone under this power is thrown into a body of icy water, they won't die from hypothermia but most likely from drowning/lack of oxygen. Likewise, I was thinking an object under this power would still burn and get 'cooked' so to speak but won't be 'burnt', but i'm not sure if that would be the case which was mainly what I wanted to know.

EDIT: Okay thank you! that's more or less the lines of what I was thinking, I wanted to make sure I wasn't being horribly wrong and it was plausible.
