The second law of thermodynamics states that no process is __1__ efficient. Thus, every system in the universe has a specific amount of energy in it. As the system functions, it will __2__ energy and thus gain __3__. Fill in the blanks

Answer 1

The second law of thermodynamics states that no process is completely efficient, implying that systems lose energy and gain entropy, moving towards disorder.

Step-by-step explanation:

The second law of thermodynamics states that no process is completely efficient. Thus, every system in the universe has a specific amount of energy in it. As the system functions, it will lose energy and thus gain entropy. This describes how with every energy transfer, some energy is lost in an unusable form, such as heat, leading to a more disordered system. The universe, therefore, trends towards increased entropy.

This reinforces the principle that a perpetual-motion machine, which would require complete efficiency, is not possible. The loss of usable energy and gain of entropy also dictates the direction of natural processes, underlining the impossibility of returning to an initial energy state.

Answer 2

1) 100%

2) Lose.

3) Entropy.

The second law of thermodynamics states that no process is 100% efficient. Thus, every system in the universe has a specific amount of energy in it. As the system functions, it will lose energy and gain entropy.

Step-by-step explanation:

The second law of thermodynamics, also known as the entropy law or heat engine law, states that the total entropy of an isolated system can never decrease over time. It either increases (for irreversible processes, that is, most real life processes) or it remains constant (for reversible processes).

This translates to an expected loss of energy for any real life process thereby making it impossible for any process to be 100% efficient. This all then leads to entropy increase (a gain of entropy).

Hope this Helps!!!
