And therefore you need to apply even more heat to melt (or vaporize) your material, since some is used for work: $\Delta U=Q-W$. Still the law of energy conversion is true. | |
| Feb 8, 2015 at 13:50 | comment | added | userkls | but isn't work always done in the case of vaporizing or melting something since there is change in volume? | |
