**Tiffany**, Wednesday, January 30, 2013 at 5:59pmYou have collected exactly 2800 aluminum cans for recycling, each with a mass of 13.6 g. How much energy is needed to melt them if their initial temperature is 26.2◦C? Assume the specific heat, the latent heat and the melting point of aluminum are 899 J/kg ·◦ C,

3.97 × 105 J/kg and 660.4 ◦C, respectively. Answer in units of J

Q= λm + cm(t-0) = λm + cmt

Water

Q=cm₁(81-t)

λ=3.33•10^5 J/kg .

m=0.123 kg

m₁ = 1.9 kg

c = 4186 J/kg •◦ C

λm + cmt= c m₁(81-t)

Solve for ‚t’
