# How much energy would it take to melt 1 aluminum soda can if the can starts out at 20°C, melts at 660°C, and has a mass of 14 g?

8,100 J

#### Explanation:

$q = m c \Delta T$

${T}_{i} = 20$°C
${T}_{f} = 660$°C
$\Delta T = {T}_{f} - {T}_{i} = 660$°C$- 20$°C$= 640$°C$= 640$K
$m = 14$g
$c = 0.900$J/g*K

(Since no specific heat capacity is provided, we can assume that the can is pure Aluminum and look up the specific heat capacity of Aluminum.)

q=(14g)(0.900J/g*K)(640K)=8,100J
