Can energy be created and destroyed? And if so what is the concept called?
According to the law of conservation of energy, energy cannot be created or destroyed, but it can be converted from one form to another. This principle is known as the conservation of energy or the first law of thermodynamics. Essentially, the total amount of energy in a closed system remains constant over time. Energy can be transformed, transferred, or stored, but it is always conserved.
Can energy be created and destroyed by ordinary physical or chemical processes? And if so what is the concept called?
No, energy cannot be created or destroyed by ordinary physical or chemical processes. The concept that describes the inability to create or destroy energy is known as the conservation of energy, which is a fundamental principle in physics. Energy can only be converted from one form to another, such as from potential energy to kinetic energy, or from chemical energy to heat energy. This conversion process is subject to the law of conservation of energy, meaning the total amount of energy in a closed system remains constant.

No, according to the law of conservation of energy, energy cannot be created or destroyed. This principle is known as the conservation of energy or the first law of thermodynamics.
The concept of the conservation of energy states that the total amount of energy in a closed system remains constant over time. Energy can only be transformed from one form to another or transferred between objects or systems, but it cannot be created or destroyed in the process.
To understand this concept, we can look at an example. Consider a light bulb - when it is turned on, it produces light and heat. The electrical energy is converted into light and thermal energy, but the total amount of energy remains the same. The electrical energy that powers the light bulb comes from a power plant, where it is generated by transforming another energy source, such as fossil fuels or nuclear reactions.
So, while energy can be converted or transferred, it cannot be created or destroyed, which is a fundamental principle in physics known as the conservation of energy.
