Calculate the mass heat capacity of a steel body weighing 2 kg, which was heated from an initial temperature of 15°C to 80°C by supplying 60 kJ of heat.

Correct answer:

c =  0.4615 kJ/kg/K

Step-by-step explanation:

m=2 kg t1=15 °C t2=80 °C Q=60 kJ  Δt=t2t1=8015=65 K  Q=m c Δt  c=m ΔtQ=2 6560=0.4615 kJ/kg/K
