Question

What is physical and chemical energy?

Answer 1

Step-by-step explanation:

"Physical energy" is related to interfering with raw physical matter (masses and bodies) and its activities, potentially and generally realizing work. Examples: General waves (radio waves, microwaves, sound waves, ocean waves, X-rays, sunlight, infrared, UVs, etc.

Chemical energy is energy stored in the bonds of chemical compounds. Chemical energy may be released during a chemical reaction, often in the form of heat; such reactions are called exothermic.

The difference between both is generally, physical changes do not involve the production of energy. Chemical changes usually involve the production of energy (which can be in the form of heat, light, sound, etc.) In a physical change, no new substance is formed. A chemical change is always accompanied by one or more new substance(s).

Answer 2

Physical energy refers to the energy present in the mechanical systems that produce force, pressure, or motion. Kinetic and potential energy are two common types of physical energy. Kinetic energy is the energy possessed by a moving object due to its motion, while potential energy is the energy possessed by an object due to its position or configuration.

Chemical energy, on the other hand, is the energy released or absorbed during a chemical reaction. Chemical energy exists in the chemical bonds of molecules and atoms. When chemical bonds are broken during a chemical reaction, energy is released, while energy is absorbed when chemical bonds are formed. An example of chemical energy is the energy stored in food. When we eat food, our body digests it and breaks down the chemical bonds in the food, releasing chemical energy which our body uses to perform various tasks.
