  1. yes, but what is the question?

    .


  2. Sounds like he wants to know the specific heat:

    Q=mc(T_1-T_2)

    Therefore:

    c = Q/m(T_1-T_2) = (1080 cal * 4.184 J/cal)/ 140g / (98.4-62.2)

    specific heat = 0.891 J/ (g -°C)
You're reading: A block of aluminum weighing 140.0 g is cooled from 98.4° C to 62.2° C with the release of 1080 cal of heat. F
