A perpetual motion machine of the second kind (PMM2) is impossible according to the second law of thermodynamics, which states that heat cannot spontaneously flow from a colder body to a hotter body without external work. PMM2 would violate this principle by converting thermal energy from a heat reservoir into work without any loss, effectively creating energy from nothing. This contradicts the concept of entropy, which dictates that in any energy exchange, the total entropy of a system and its surroundings will either increase or remain constant, but never decrease. Thus, such a machine cannot exist.

What is physically impossible?
It is physically impossible to travel faster than the speed of light in a vacuum, as predicted by Einstein's theory of relativity. It is also impossible to create or destroy energy, but only to convert it from one form to another in accordance with the law of conservation of energy. Additionally, perpetual motion machines that produce more energy than they consume are also considered physically impossible due to the laws of thermodynamics.
What law of thermodynamics accounts for the other 75 units of energy?
The way that the question is worded it is impossible to be sure exactly what you are looking for, but as a reasonable guess, you are looking for what happens to energy that is not producing useful work. The second law of thermodynamics generally tells us that we can never get 100% efficiency, i.e. we can never convert all the energy we are using into useful work. Some of the energy will just go into increasing the entropy of the universe.
Is thermodynamics the same as physical chemistry?
Thermodynamics is considered a part of physical chemistry.
What is the study of conversion of heat to mechanics?
The study of converting heat into mechanical energy is called thermodynamics. It is a branch of physics that deals with the relationships between heat, work, and energy. Thermodynamics is essential for understanding and optimizing processes such as engines, refrigeration, and power generation.
What law of thermodynamics is unavailable for doing work?
"Unavailable for doing work" is related to the Second Law of Thermodynamics.
What if you did not have energy on earth?
Third law of thermodynamics says that it's impossible to have zero energy ever.
How do plants break the second law of thermodynamics?
They don't. Breaking any of said laws is by definition impossible.
How does the 2nd law of thermodynamics make evolution impossible?
The second law does NOT make evolution impossible. It just requires that as evolution takes place that there be an increase in entropy of the universe as a whole.
Which is an impossible value of efficiency for a heat engine?
100% efficiency is impossible for a heat engine working between two reservoirs at different temperatures according to the second law of thermodynamics.
What is the third law of thermodynamics, which states that no system can reach absolute zero temperature?
The third law of thermodynamics states that as a system approaches absolute zero temperature, its entropy approaches a minimum value. This means that it is impossible for any system to reach absolute zero temperature.
Why is perpetual motion impossible because it violates the laws of thermodynamics?
Perpetual motion is impossible because it goes against the laws of thermodynamics, specifically the law of conservation of energy. This law states that energy cannot be created or destroyed, only transferred or converted. Perpetual motion machines claim to generate energy indefinitely without any external input, which contradicts this fundamental principle of physics.
What is physically impossible?
It is physically impossible to travel faster than the speed of light in a vacuum, as predicted by Einstein's theory of relativity. It is also impossible to create or destroy energy, but only to convert it from one form to another in accordance with the law of conservation of energy. Additionally, perpetual motion machines that produce more energy than they consume are also considered physically impossible due to the laws of thermodynamics.
What is the significance of the reversal of the second law of thermodynamics in the context of entropy?
The reversal of the second law of thermodynamics would mean that entropy, which tends to increase in a closed system, would instead decrease. This would have significant implications for the behavior of energy and matter in the universe, potentially allowing for processes that are currently considered impossible.
