🤓 Based on our data, we think this question is relevant for Professor Block's class at Central Piedmont Community College.
The following information is given for tin at 1 atm:
Tb = 2270.00°C ΔHvap (2270.00°C) = 1.939 x 103 J/g
Tm = 232.00°C ΔHfus (232.00°C) = 59.60 J/g
Specific heat solid = 0.2260 J/g°C
Specific heat liquid = 0.2430 J/g°C
A 26.40 g sample of liquid tin at 497.00°C is poured into a mold and allowed to cool to 25.00°C. How many kJ of energy are released in this process? (Report the answer as a positive number.)
