If you can post your working for the first problem, you can get help on that if you need.

For the second part calculate the heat required for each step:

1)  Melt the metal which is at 330.1C into a liquid
2)  Heat the liquid metal to its melting point at 1541C
3)  Heat the metal to a vapor

You should have an equation for this type of problem.  Something like:  Q = cm :delta: T

I figured out the first one, but I'm still really confused about the temperature changes in the 2nd one. I don't know where to start

Dear erin329;

Can you try to use the recipe from macman104 and the praxis in the following thread to start to solve your problem, and show me with your work where you run in troubles?:

Good Luck!

ok it just hit me! I was trying to use too many temperature conversions when there was only one. I figured it out! Thanks for your help though!
