second law
That law is known as the Law of Conservation of Energy. It is also known as the First Law of Thermodynamics.
The 1st Law of thermodynamics is a restatement of the law of conservation of energy.
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").
Conservation of energy is the 1st law of thermodynamics.
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.
The First Law of Thermodynamics.
It is called the First Law of Thermodynamics, sometimes also called The Law of conservation 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.
That's related to the First Law of Thermodynamics - the Law of Conservation of Energy.
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.
The First Law of Thermodynamics is the Law of Conservation of Energy. There is a quantity, called energy, which does not change (in a closed system). There are several types of energy, and it is possible to convert from one type of energy to another; but never will the total energy change.
Usually yes. The energy isn't entirel "lost" - in the sense of the First Law of Thermodynamics it is still there. However (in the sense of the Second Law of Thermodynamics) it gets converted to a lower-quality energy, that can no longer be used, so for all practical purposes it is lost.
