 P: 48 1. The problem statement, all variables and given/known data How much energy is required to change a 35 g ice cube from ice at −15 C to steam at 117 C? The speciﬁc heat of ice is 2090 J/kg * C, the speciﬁc heat of water is 4186 J/kg * C, the speciﬁc heat of stream is 2010 J/kg * C, the heat of fusion is 3.33 × 10^5 J/kg, and the heat of vaporization is 2.26 × 10^6 J/kg. Answer in units of J. 2. Relevant equations Q=m*L Q=m*c*$$\Delta$$T 3. The attempt at a solution 35g*15C*2090J/kg*C - heat to raise ice's temp. to freezing + 3.33 * 10^5 J/kg *35g - heat to melt ice into water + 100C *4186J/kg*C *35g - heat to raise water temperature to boiling + 2.26*10^6 J/kg* 35g - heat to boil water into vapor + 2010 J/kg*C *117C *35g - heat to make vapor rise to 117 C =114734 J I tried this answer and the program says it's incorrect, what am I doing wrong?
