Answer to Question #190224 in Civil and Environmental Engineering for John Prats
Question #190224
How much heat is required to totally melt 6 kg of aluminum which is at 30 °C.
Expert's answer
aluminium has a specific heat of 0.9KJ/KgK, a melting point of 660 degrees Celsius
Formula adopted
dQ= m c dt
m=6kg
c=0.9KJ/KgK
dt=660-30=630 deg celcius=630+273K=903K
dQ= 6* 0.90*903=4876.2kJ
