I think they mean that you need to put energy in your product and thus the product itself needs to be on a higer energy level.
Or is there another reason why they state this?
besides that: can you have sublimation of a product of the energy around the product is higher?
I think yes, because the environment around the product can then put his energy in the product and thus cause sublimation, but is this correct? It seems a bit strange and a circle movement (=> energy from outside in the product to sublimate it, and by sublimating it you will get vapor with a lot more enery outside the product and thus making the energylevel outside higher again (note that this is in a closed environment, otherwise the engery could go away...?)
any ideas?
