During muscle contractions, chemical energy is converted to kinetic energy of movement and also to thermal energy, which dissipates into the surroundings as heat.With respect to the second law of thermodynamics, which event occurs in this example?

Question

Quizplus · Accepted Answer

The second law of thermodynamics states that entropy tends to increase in a closed system. In this case, the conversion of chemical energy to both kinetic and thermal energy results in an increase in entropy as heat is dissipated into the surroundings. Therefore, choice B is the best answer.

During Muscle Contractions, Chemical Energy Is Converted to Kinetic Energy
