What is the difference between endothermic and exothermic reactions?
If energy is released as a result of a process, an exothermic change has taken place. If a constant input of energy is required to drive a physical or chemical change, the change is described as endothermic.
Is a firecracker exploding a endothermic or exothermic?
The explosion of a firecracker is exothermic, as it releases energy in the form of heat, light, and sound. This reaction happens when the chemical bonds in the explosive materials break to form new compounds with lower energy levels, resulting in the release of energy into the surroundings.
What is the difference between endothermic and exothermic And give examples?
Chemical reactions that release energy in the form of heat, light, or sound are called exothermic reactions. Example: Mixture of sodium and chlorine to yield table salt In other words, combination reactions are exothermic. Reactions that absorb energy or require energy in order to proceed are called endothermic reactions. For example: In the process of photosynthesis, plants use the energy from the sun to convert carbon dioxide and water to glucose and oxygen.
Does exothermic create more energy?
No, it releases energy to it's surroundings!
What term is used to describe the effect of sound on molecules in which each excited molecule returns to its steady state after passing its energy to its neighboring molecule?
The term used to describe this effect is "sound propagation" or "acoustic propagation." In this process, sound waves cause molecules in a medium to vibrate, transferring energy from one molecule to its neighbor. Each molecule returns to its original state after passing the energy along, allowing the sound wave to travel through the medium. This phenomenon is fundamental to how sound is transmitted in gases, liquids, and solids.

Is breaking glass endothermic or exothermic?
i think it is nothing
What is endothermic and exothermic reaction?
Endothermic; that reaction in which energy is absorbed is called endothermic reaction, mostly the breaking of a molecule is an endothermic reaction, as for breaking process energy is required, when a molecule gets the sufficient energy it breaks. EXOTHERMIC Reaction is that in which energy is released, as combining of any two element or atoms to make a molecule, take the example of formation of CO2.
What is an another name for exothermic and for endothermic reactions?
it is a Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive. There are other chemical reactions that must absorb energy in order to proceed. These are endothermic reactions. Endothermic reactions cannot occur spontaneously. Work must be done in order to get these reactions to occur. When endothermic reactions absorb energy, a temperature drop is measured during the reaction. Endothermic reactions are characterized by positive heat flow (into the reaction) and an increase in enthalpy (+ΔH).
What does exothermic mean in terms of thermodynamics?
Exothermic means that heat energy is given off from the reaction. In turn this means that the enthalpy (stored chemical energy) decreases. Best example of an exothermic reaction is combustion reactions (reacting with oxygen, or even more simply: burning). The opposite of exothermic is endothermic.
What is the difference between endothesmic and exothesmic change?
I'd think the question is meant to be about: endotheRmic and exotheRmic.The word endothermic ("within-heating") describes a process or reaction in which the system absorbs energy from the surroundings in the form of heat.The term exothermic ("outside heating") describes a process or reaction that releases energy from the system, usually in the form of heat.Energy involved can also be in the form of light (e.g. a spark, flame, or explosion), electricity (e.g. a battery), or sound (e.g. burning hydrogen).

What is propagation in science?
Propagation in science refers to the process by which something spreads or moves through a medium. This can refer to the transmission of light, sound, or wave energy. In biology, propagation can also describe the reproduction or multiplication of living organisms.
What would the process be called that releases energy?
The process is called metabolism. The mitochrondria function as energy breakdown organelles in the cell. The term for aerobic metabolism is cellular respiration.
What do you mean by propagation of sound?
Propagation of sound in a medium (like the atmosphere) is the collision between the medium particles driven by a vibrating object
Does exothermic create more energy?
No, it releases energy to it's surroundings!
