I put 3.5g of potassium chloride (KCl) in one test tube with 10 mL of water. I put it on a constant temperature bath at 80 degrees Celsius. Some of the potassium chlorate dissolved and some of it remained solid. Once all of it had dissolved, I took it off the bath, and let it cool down. I recorded the temperature at which the potassium chloride just began to crystallize. (It was 23.95 degrees C) I repeated this with three other beakers- one with 4g of potassium chloride, one with 4.5g and one with 5g.

My two questions are-
Why is it important to not allow the test solutions to boil?

and

Why is it better to determine the initial crystallization temperature during cool down rather than the temperature at which all of the salt dissolves?

Lets say I'm using an IGBT. I have it hooked up like a MOSFET inverter lets say. If I have the source energized with AC, and I apply a DC current to the gate, will I get AC as output, will the IGBT rectify the output current, or will I get DC riding over AC?

I think this is the right catagory to ask this in. I know it is possible to generate an EMP without the nuclear explosion, but is it possible to generate one large enough to say take out an entire country? Like North Korea or some other hostile place? How would this be accomplished?
