endothermal
/,endou'θə:məl/ Cách viết khác : (endothermic) /,endou'θə:mik/
Definition
- Adjective:
- (Chemistry) Absorbing heat: Describes a chemical reaction or process that takes in heat from its surroundings.
- (Biology) Relating to endothermy: Pertaining to organisms (endotherms) that maintain a constant body temperature through internal metabolic processes, often by generating heat.
Usage
- The term is primarily used in scientific contexts, especially chemistry and biology.
- In chemistry, it describes reactions that feel cold because they absorb energy.
- In biology, it describes animals (like mammals and birds) that regulate their body temperature internally.
Examples
- Chemistry Context:
- The melting of ice is an endothermal process because it requires heat from the environment.
- Scientists studied the endothermal reaction to understand its energy requirements.
- Biology Context:
- Mammals are endothermal creatures, capable of maintaining a stable body temperature in cold climates.
- The endothermal nature of birds allows them to be active during winter.
Advanced Usage
- "Endothermal reaction": A specific chemical reaction characterized by a positive change in enthalpy (ΔH > 0), meaning it absorbs heat.
- In the lab, we measured the temperature drop during the endothermal reaction.
- "Endothermal organism": An organism that is an endotherm.
- The research compared the energy expenditure of endothermal organisms with that of ectotherms.
Variants and Related Words
- Endothermic (adj): The more common variant, synonymous with "endothermal" in both chemistry and biology.
- The decomposition of limestone is an endothermic process.
- Endotherm (n): An organism that generates heat to maintain its body temperature.
- Humans are classified as endotherms.
- Endothermy (n): The physiological characteristic of being warm-blooded.
- The evolution of endothermy was a major step for mammals.
Synonyms
- Heat-absorbing: (Chemistry) Taking in thermal energy.
- Warm-blooded: (Biology) Maintaining a constant warm body temperature (common, but less precise than endothermic/endothermal).
Antonyms
- Exothermal/Exothermic (adj): (Chemistry) Releasing heat. (Biology) Ectothermic.
- Burning wood is an exothermic reaction.
- Ectothermic (adj): (Biology) Relying on external heat sources to regulate body temperature.
- Reptiles are typically ectothermic animals.
Adjective
-
(of a chemical reaction or compound) occurring or formed with absorption of heat
