You have entered a 5K race. As you finish the last 50 meters, you are breathing harder than at the start of the race and sweating profusely. This is an example of the law of thermodynamics because is increasing.

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.

answer: national resource conservation services

national resource conservation services is the us. based approach that provides technical and financial assistance for natural resource management. nrcs society in conservation of resources by involving in activities like farmland protection, flood prevention, watershed protection, urban conservation, conserves economic and environmental conditions. it conducts soil surveys and implements the policy of natural resources management on the society.
