What law of thermodynamics states that heat is a natural by-product of most energy conversion processes?

This is related to the Second Law of Thermodynamics.


Does a heat engine of efficiency 100 percent necessarily violate the first and second law of thermodynamics?

A heat engine of 100 percent efficiency violates the second law of thermodynamics and is impossible even in theory.


What conversion does the second law of thermodynamics not allow?

The second law does not allow complete conversion of heat into work.


How does the 2nd Law of Thermodynamics relate to the direction of heat flow?

The second law of thermodynamics states that heat will always flow from a region of higher temperature to a region of lower temperature.


According to the second law of thermodynamics heat energy released by an organism is .?

During the photosynthesis light energy in chemical bonds What also happens according to the predictions of the second law of thermodynamics?

heat is released in the pocess.


Which law of thermodynamics states that the heat engine cannot be completely efficient?

That is a consequence of the second and third laws of thermodynamics.


What is second law of themodynamics?

Law of thermodynamics deals with the heat energy involved in a reaction. According to second law of thermodynamics, the energy system tries to increase the entropy. The entropy is a measure of chaos of molecules.


Is it a violation of second law of thermodynamics to convert heat completely into work?

Yes - the second law states that heat cannot be completely converted into useful work.


When energy is transformed some is used but most is released as unusable heat energy according to which law of thermodynamics first second third or universal?

The closest law is the Second Law of Thermodynamics. Note that not necessarily "most" energy will be converted to unusable heat, but it is almost inevitable that some will.


According to the second law of thermodynamics heat energy released by an organism is?

Gone forever


What is permitted based on the second law of thermodynamics?

heat being completelyconverted into mechanical energy


First and second laws of thermodynamics?

The first law of thermodynamics is: Energy cannot be made or destroyed. But heat energy can be used to power movement energy, and movement energy can turn into heat energy. The second law of thermodynamics is: Heat energy always moves from hot things to cold things (this is why the sun will heat up cold lemonade if the lemonade is left outside on a hot day).


Which thermodynamic law says that you cannot convert 100 percent of a heat source into mechanical energy?

second law of thermodynamics


According to the second law of thermodynamics it is not possible to change heat completely into work with no other change taking place?

True


What is formulations of the second law of thermodynamics?

Heat cannot of itself pass from a colder body to a hotter body.


How does energy efficiency relate to the first and second law of thermodynamics?

By the first law of thermodynamics, energy is conserved - i.e. the sum of the useful work and the energy lost to heat will equal the energy you started with. The second law states that you will never get 100% energy efficiency.


What is matter and energy second law of thermodynamics?

The second law of thermodynamics states essentially that it is impossible for heat to flow from a cooler body to a hotter one, without the performance of work by an external agency. I'm not sure how this relates to your wording of 'matter and energy'.


Is conservation of energy involved in the second law of thermodynamics?

It is assumed as part of the second law, but the second law is really all about what happens to the energy as it changes form. If energy were not conserved (1st Law), then it might be possible to violate the second law by magically creating some energy out of nowhere to allow the work coming out of a system to be equal to the energy input even when some is lost to heat.


In which direction does heat energy travel?

By the second law of thermodynamics, heat will travel spontaneously from regions of higher temperature to regions of lower temperature when they come into contact.


Does heat flow from warm to cooler substances?

Yes. Heat flows from a warmer to a cooler substance. The technical term is: The Second Law of Thermodynamics.


How do the first and second laws of thermodynamics relate with to the law of conservation of energy?

As stated by the expert: The First Law of Thermodynamics IS the Law of Conservation of Energy. The Second Law of Thermodynamics is not directly related; however, it provides additional restrictions, as to what can, and what cannot, be achieved.


When the law of conversation of energy is applied to heat it is known as the law of thermodynamics?

Not exactly. The first law of thermodynamics, i.e. the law of conservation of energy, also accounts for heat as one of the many forms that energy can take. There is no one law called "the law of thermodynamics", but there are several "Laws of Thermodynamics" (note the plural form "LAWS").


Practical applications of first law of thermodynamics?

Application of first law of thermodynamics is in engine, refrigerator,heat pump.
