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[itex]\Delta[/itex]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?! Thanks in advance!!
