Becasue there are only 26 letters of the [Roman] alphabet and more than 4 times that number of elements.
The energy in food is measured in kilo calories it is abbr. by CAL one calorie is abbr. cal. The case is the key.
I must assume that the ice block is at an initial temperature of 0o C. I also need to work in joules,. so I will convert the calories to joules. 1600 cal. (4.184 joule/1 cal.) = 6694.4 joules -------------------- 6694.4 J = (20 grams H2O)(4.180 J/gC)(Tf - 0o C) 6694.4/83.6 = Tf = 80o Celsius ==========
According to Perrys Chemical Engineers Handbook 62.7 cal/(ºC.mol) @ 282K (~8.85ºC) which converts to 1.05 J/(ºC.g) conversion: 4.184 J/cal 294.691 g/mol
The specific heat of copper is 0.093 cal/g(C°) or 390 J/kg(C°).
The heat of fusion (aka enthalpy of fusion) of ice at 0 °C is about 79.72 cal/g. The specific heat of water in the range from 30 °C to 0 °C is about 1 cal/g/°C. The total energy that must be removed is thus: 20.0 g x[(0-30)°C x 1 cal/g/°C - 79.72 cal/g] = -2184 cal in other words you must remove 2184 cal to take 20.0 g of water from liquid at 30 30 °C to solid (ice) at 0 °C.
