The specific heat of wood is about 1,700 J/ kg• °C. How much energy is required to heat a 12 kg piece of wood from 20°C to 30°C?
A)1,400 J
B)17,000 J
C)204,000 J
D)612,000 J

The energy required can be calculated using the formula: Q = mcΔT, where m = 12 kg, c = 1,700 J/kg°C, and ΔT = 30°C - 20°C = 10°C. Thus, Q = 12 kg * 1,700 J/kg°C * 10°C = 204,000 J.
