# Drawing a heat curve of ice melting

1. The problem statement, all variables and given/known data

2. Relevant equations
equation with each part.

3. The attempt at a solution
I did part a) b) and c) on my own:

Part d:
I am having trouble at this part. I understand how to draw the heat curve but I am confused on what numbers I should use for the x-axis of the graph. I know that I have to start off with 225 s at 0°C, and then keep the line flat until about 1403 s, but I don't know what numbers to use from there...

any help would be appreciated :)
Thanks.

After the ice has all melted, what does it become? If you keep adding heat to the melted ice, can't you continue to draw a curve of temperature versus time?

It becomes, liquid (water), then boils, then turns to gas. I understand this part but what I don't get is what values of time should I put on the x-axis, like how long does it take for each phase to change. ex. from a water to boiling....

Well, what information do you need to complete the curve? Assume the heater is still putting out 70 W.

I finally figured it out!
Here is my graph:

Thanks so much for the help!
