Question

During photosynthesis, light energy is converted to the energy in chemical bonds. What also happens according to the predictions of the second law of thermodynamics?

Question 20 options:

chemical energy is converted to light energy

matter is lost in the process

heat is released in the process

the light and chemical energy are equal

Answer 1

According to the predictions of the second law of thermodynamics "heat is released in the process".

Step-by-step explanation:

The "second law of thermodynamics states that total entropy of the isolated system can never be decreased over but is constant if all processes are reversible". Similarly in photosynthesis not all the energy are taken by the plants, some reflected and some are lost as well. However, the loss of energy to the surrounding results in increase of entropy. The energy used in the photosynthesis is the light. The source of this light is sunlight.
