First Law of Thermodynamics: Energy can be converted from one form to another, but cannot be created or destroyed.
Second Law of Thermodynamics: The second law of thermodynamics states that for any process occurring in a closed system, the entropy increases for an irreversible system and remains constant for a reversible system, but never decreases.

∙ 12y agoThe 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 law of thermodynamics states that the heat engine cannot be completely efficient?
True
What are the laws of energy conversion?
Those would basically be the First and Second Laws of Thermodynamics. The First Law (energy conservation) states that the total energy can not be increased or decreased. The Second Law imposes some limitations about what conversions are possible.
What is the constraints of energy?
The usual constraints are the First and Second Laws of Thermodynamics: First: energy is conserved; and second: useful energy gets converted into unusable energy - not the other way round.
The fact that usable energy is always lost in an energy transfer is due to what 1 Newton's first law of motion 2 the second law of thermodynamics 3 Newton's second law of motion 4 the first l?
The second law of thermodynamics.
Why the first and second law of thermodynamics may be states you can not get ahead and you can not break even?
According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.According to the second law of Thermodynamics, the amount of usable energy will continuously decrease.
Which two laws in the universe govern all processes involving heat and energy?
The first and second laws of thermodynamics.
Which law of thermodynamics states that the heat engine cannot be completely efficient?
True
What is universal law of energy?
There is no commonly accepted law by that name, as far as I know. Two important laws about energy are the First Law of Thermodynamics and the Second Law of Thermodynamics.
What forces are used in sport?
Gravity, the First and Second Laws of Thermodynamics, etc.
How many thermodynamics laws are there?
Basically four: the zeroeth law, the first law, the second law and the third law.
Why can't electric suppliers use electric motors to spin the generators?
If you are suggesting a "perpetual motion" scenerio, it would violate the first or second laws of thermodynamics. Many inventors dream of perpetual motion machines, but they are an impossible dream according to the laws of thermodynamics. The second law of thermodynamics says that an engine or process of any type must always have an efficiency of less than 100%. A perpetual motion machine that uses a generator to power the motor that runs the generator requires both the generator and motor to operate with 100% efficiency. This type of perpetual motion machine does not violate the first law of thermodynamics, but violates the second law of thermodynamics. It is a perpetual motion machine of the second kind because it violates the second law of thermodynamics. Not even the cleverest engineer or inventor can build a perpetual motion machine because it would violate either the first or second law of thermodynamics, which are fundamental laws of physics.

Why Zeroth law of thermodynamics is not called as 3 Rd law of thermodynamics though it was discovered after 1 and 2 law?
It was found to be more fundamental than the other laws. It should therefore be the first law, but at that time, renumbering all the laws was deemed impractical, since the terms "First Law" and "Second Law" were already well-established.
