Answer:
The correct answer is - second, entropy.
Explanation:
The second law of thermodynamics states that the change of energy from one to another form or move from one system to another system the entropy in a closed system increases. Entropy exhibits if a particular reaction is going to be spontaneous or not.
In start of the race the energy that is used very low and the entropy is at it is starting point, however by the end of the race the entropy is increasing that suggests it follows the second law of thermodynamic.
Thus. the correct answer is - second, entropy.
