# Homework Help: Thermodynamics - again, Part of the ice that melt :S

### Planck const

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

Stamp of iron the his mass - M and temp' - T0 (T0>100 C deg') has been placed on cube of ice.

The mass of the ice - m, the temp' - t0 = 0 C deg'

How many present of the ice get melt?

2. Relevant equations

Q = mc$\Delta$t

3. The attempt at a solution

If I let all the ice getting melt, I got one equation with one unknown size - T (end)

But if I define constant K that representative the presents of the ice that melt... I got two unknown sizes - K and T (end)

What I supposed to do?!
