: endotérmico

An endothermal reaction occurs when energy is absorbed, often resulting in a cooler environment.

Examples

Hence, this combination of exothermal (combustion) and endothermal (gasification) reactors makes the whole system an auto-thermal process.

Academic text (2018)
The reaction was classified as endothermal because it absorbed heat during the process.
During the experiment, the endothermal reaction caused the surrounding temperature to drop significantly.

Morphology

endothermal = thermal (semi-transparent) = endo + thermal

Formed by the combining form 'endo-' + 'thermal' in a technical scientific sense; the pattern is regular but 'endo-' is a specialized combining form that many B1 learners may not know.

Etymology

Endothermal comes from the Greek parts endo- meaning 'within' and thermal meaning 'heat', like in thermal clothing or thermometer. So an endothermal reaction takes heat 'into' itself from its surroundings, which is why it absorbs heat.
