  07.39: A mass of materia- bnh4 3u+0,lkwjf+30pvqua)7z pu c.qegehml exists in its solid form at its melting temperature $10^{\circ}C$. The following processes then occur to the material:
Process 1: An amount of thermal energy Q is added to the material and $\frac{3}{4}$ of the material melts.
Process 2: An identical additional amount of thermal energy Q is added to the material and the
material is now a liquid at $500^{\circ}C$.
