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 degrees * c to 30 degrees * c ?

204 kJ

Explanation:

Heat energy can be calculated using

Q=mcθ

where Q = Heat energy

           m =mass

           c = specific heat capacity

           θ =temperature difference

Q = 12 * 1700*10

   = 204000 J

   = 204 kJ
