Question 4 unsaved energy is being added when a pot of water is boiling on the stove. why doesn't the temperature of the water rise? where is the energy going? question 5 what questions do you have about this? are you confused? have any other feedback?

Question 4:
some of the energy is being used to change the state of some of the water.

At some places in the pot, usually at the bottom right next to the fire, water
at 100°C is changing to steam at 100°C.  That "phase change" takes energy,
and the temperature doesn't change.

Question 5:
I have no questions about this. I understand it well enough for the time being.
I am confused by many things, but a pot of boiling water is not one of them.
I have no important feedback at this time, but please check back with me
in a week or two. 
Thank you. 

Your answer is c. explanation: plasma  is the fourth state of matter, derived from the gaseous state of matter.  plasma  can contain free  electrons  and/or  ions. while  plasma is never neutral, it can either be positively or negatively charged.  gases, however, are electrically neutral.
