Aluminum is melted during the recycling process.
A) How much heat must be transferred to each kilogram of aluminumto bring it to its melting point, 660 degree Celsius, from roomtemperature, 20 degree Celsius?
(I subtracted from 660 - 20 = 640 degree Celsius; Specific Capacityof Aluminum is 890 J/kg - degree Celsius
Then I used this equation Q=CmÎT --> Q=(890J/kg-degreeCelsius)x(1 kg)x(640 degree Celsius) = 569600 J I don't know ifthis is the right answer for this question.)
B) About how many cups of coffee could you make with muchenergy?
(I need help with question.)
