Question

1. A steel cube whose V_o =2.5 m³, is originally at 16^oc. It is heated to a final temperature of 35^oc.

          Determine: (a) ∆V_f of the cube; (b) the ∆Q required to raise the cube’s        temperature.

          Assume: M_cube =1.97 x 10⁴ kg = 1.97 x 10⁷ g; β_steel = 33 x 10^-6 1/^oc;

Csteel = 450 J/kg-^oc = 1884 cal/kg-^oc
