In one box of nails, there are 75 iron nails weighing 0.280 lblb . The density of iron is 7.86 g/cm3g/cm3. The specific heat of iron is 0.452 J/g∘CJ/g∘C. The melting point of iron is 1535 ∘C∘C. A)How much heat, in joules, must be added to the nails in the box to raise their temperature from 16 ∘C∘C to 123 ∘C∘C? B)How much heat, in joules, is required to heat one nail from 31 ∘C∘C to its melting point?
