2nd law of thermodynamics

Postby Peter Nguyen 2I » Sun Feb 03, 2019 6:07 pm

Can someone explain the second law of thermodynamics and how it relates to what we are doing?

it says that the total entropy of an isolated system is always increasing. Basically, the more that energy is transformed, the more energy is wasted.

The second law of thermodynamics says that when energy changes from one form to another, entropy (or disorder) increases. I think this can help us understand how the systems are changing through reactions.

the second law says that energy transformation is not 100% efficient, the degree of disorder of the universe increases with every transformation

Like what was said above, the 2nd law states that entropy is always increasing. Over time, or as a reaction progresses, usable energy is irretrievably lost as unusable energy (heat lost to the environment, etc.) increases.

Entropy increases, and as the amount of energy used decreases, the amount of energy not used increases
