Question

the energy stored in a wooden log transforms when the log is burned. which of the following explanations best describes how the chemical energy stored in the log compares to the heat and light energy produced by burning? the chemical energy is more than the amount of heat, light, and other applicable energies. the chemical energy is less than the amount of heat, light, and other applicable energies. the chemical energy stays the same and additional energy is produced as heat, light, and other applicable energies. the chemical energy is equal to the amount of heat, light, and other applicable energies.

Explanation:

According to the law of conservation of energy, energy cannot be created or destroyed, only transformed. When a wooden log burns, the chemical - energy stored in it is transformed into heat, light, and other forms of energy. The total amount of energy before and after the transformation remains the same. So the chemical energy in the log is equal to the amount of heat, light, and other applicable energies produced.

Answer:

The chemical energy is equal to the amount of heat, light, and other applicable energies.
