Let's say that everything is an example of the Law of Conservation of Energy - because this is a law that has never been seen to fail. More specifically, in any energy conversion, one type of energy gets reduced; another type of energy inreases in the same amount.
The Law of Conservation of energy states that energy cannot be created or destroyed; in other words the total amount of energy in the universe would remain constant. (: My source is the Physical Science with Earth Science textbook, Chapter 5: Energy. (:

chemical energy to heat energy
This statement is based on the second law of thermodynamics, which states that in any energy transformation, some energy is lost as waste heat and cannot be converted back into usable energy. This principle underlies many natural processes and technological systems.
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.
Large amounts of energy are expended
Any time there is an energy conversion, a certain amount of one type of energy gets reduced, and another type of energy increases. The amounts lost and gained are the same, so total energy is conserved.
The concept that energy cannot be created or destroyed is a fundamental principle known as the Law of Conservation of Energy. It is a universal law of physics that applies in all states and is not specific to any particular state's energy laws.
The law of conservation of energy might apply to an energy conversion that you observe in your daily life for example if you have something on the table and you push it or move it with your arm
In a dry cell, chemical energy is converted into electrical energy. This energy conversion occurs through chemical reactions within the cell that produce a flow of electrons, generating an electric current.
The conversion of potential energy in coal into kinetic energy that heats steam is an expression of the first law of thermodynamics, which states that energy cannot be created or destroyed, only transferred or transformed. In this case, the potential energy stored in coal is transformed into kinetic energy in the form of heat to generate steam power.
The principle you are referring to is the second law of thermodynamics, which states that in any energy conversion process, some energy is lost as waste heat, resulting in a decrease in the overall usefulness of the energy.
Electromechanical energy conversion involves the conversion of electrical energy to mechanical energy and vice versa. Key principles include Faraday's Law of electromagnetic induction, which explains the generation of voltage in a coil due to a changing magnetic field, and Lenz's Law, which states that the induced voltage opposes the change in magnetic flux. Additionally, the Lorentz force law describes the force on a current-carrying conductor in a magnetic field, resulting in the movement of the conductor.
Energy conversion is the process of changing one form of energy into another. It occurs in various ways such as mechanical to electrical energy in a generator or chemical to thermal energy in combustion. The law of conservation of energy states that energy cannot be created or destroyed, only converted from one form to another.
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.
Thermal energy is always produced in energy conversions due to inefficiencies in the conversion process. Some of the original energy is always lost as heat due to friction, resistance, and other factors. This is known as the Second Law of Thermodynamics.
