My girlfriend's daughter is having a test on the subject and she needs a digital photo of each 3 stages and a material that does so. Can you give me examples? I appreciate it.
I doubt that you can see plasma, just as you can seldom see gasses.... A speck of dust entering the atmosphere becomes plasma as its atoms are ripped off one by one, but in returning to a lower state of matter, they give off electro-magnetic radiation, some of which we see as light, as a shooting star...The difference between states of matter is heat.. The notion of global warming does not give most people any grasp of the energy that must be applied to ice to make it water, or how much must be added to water to make steam... It is easier to change the climate of the earth than it is to change human behavior, but I trust that we will change when we find it is both too late, and necessary; and not without resistence from some up until the very end...
