Question

in a wood biomass power plant, wood waste is burned. the resulting energy heats water, producing steam. the steam causes turbines to spin. the spinning turbines run an electric generator. in this type of power plant, what type of energy transformation occurs from the wood biomass to the heated water?
a) electric to kinetic
b) thermal to electric
c) chemical to thermal
d) kinetic to gravitational

Explanation:

Wood biomass has chemical energy. When burned, this chemical energy is released as heat (thermal energy) to heat the water. So the energy transformation from wood biomass (chemical) to heated water (thermal) is chemical to thermal.

Answer:

C. Chemical to thermal
