As ice melts at Standard pressure, its temperature remains at 0 degrees C. until it has melted. Its P.E._____?

*P.E.= Potential Energy





A) remains the same


B) increases


C) Decreases

As ice melts at Standard pressure, its temperature remains at 0 degrees C. until it has melted. Its P.E._____?
B increases. is correct.





Potential energy is that energy which causes a change in state [ie from solid to liquid to gas] without causing a change in temperature.





As you heat water to boiling point and it reaches 100C, you have to continue putting heat into it to boil it.





BUT you will never get it to go above 100C however much heat you put into it.





This 'lost' heat is potential energy and is going to change the state, not raise the temperature.





Just remember that as things change state, as they go up in temperature or go from solid to liquid to gas they GAIN potential energy.





As they go down, from gas to liquid to solid they lose potential energy.





It is this energy that keeps them in the state they are in.

it may be: C


like i said im not truly sure if this is right or not, just a guess
