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
