What does exothermic mean in biology?
In thermodynamics, the term exothermic process (exo- : “outside”) describes a process or reaction that releases energy from the system to its surroundings, usually in the form of heat, but also in a form of light (e.g. a spark, flame, or flash), electricity (e.g. a battery), or sound (e.g. explosion heard when burning …
What does endothermic mean in zoology?
Endotherm, so-called warm-blooded animals; that is, those that maintain a constant body temperature independent of the environment. The endotherms primarily include the birds and mammals; however, some fish are also endothermic.
What does exothermic reaction mean in science?
heat
An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.”
What does endothermic mean in biology?
To be endothermic, an organism must produce its own body heat through metabolism. This means that the endothermic organism can maintain internal homeostasis regardless of the external environmental temperature. This type of organism is called an ectotherm and commonly referred to as being cold-blooded.
What is the most exothermic reaction?
Common iron rust reacts with aluminum to create corundum and molten iron.
Which is the best definition of the word exothermic?
exothermic (comparative more exothermic, superlative most exothermic) (chemistry, of a reaction) That releases energy in the form of heat. (chemistry, of a compound) That releases heat during its formation, and absorbs it during its decomposition. (zoology) Of an animal: whose body temperature is regulated by external factors; cold-blooded.
How are exothermic processes related to the law of Conservation of energy?
Exothermic and Endothermic Processes. When physical or chemical changes occur, they are generally accompanied by a transfer of energy. The law of conservation of energy states that in any physical or chemical process, energy is neither created nor destroyed. In other words, the entire energy in the universe is conserved.
How does an exothermic animal get its heat?
Exothermic animals receive the heat from the external sources. They cannot generate their own heat and use the energy of the sun. The temperature of their bodies can vary according to the temperature characteristics of the surroundings (Bekoff & Byers, 1998).
How is change in enthalpy related to an exothermic reaction?
In an exothermic reaction, change in enthalpy ( ΔH) will be negative. Therefore, it can be understood that the net amount of energy required to initiate an exothermic reaction is less than the net amount of energy released by the reaction. When a calorimeter, a device used to measure the heat released by a chemical reaction,
