tỏa nhiệt

Phản ứng hóa học này tỏa nhiệt ra môi trường xung quanh.

Definition

1. Verb:

   • To emit heat: To release or give off thermal energy, often as a result of a chemical reaction, physical process, or combustion.
   • To radiate heat: To disperse heat outward from a source into the surrounding environment.

2. Noun (in compound forms):

   • Heat emission / Exothermicity: The process or property of releasing heat. Often used in technical contexts like "năng suất tỏa nhiệt" (heat emission capacity).

Usage Examples

• Verb:
  • Phản ứng này tỏa nhiệt rất mạnh. (This reaction emits heat very intensely.)
  • Mặt trời tỏa nhiệt và ánh sáng. (The sun radiates heat and light.)
  • Lò sưởi đang tỏa nhiệt khắp phòng. (The heater is radiating heat throughout the room.)

Advanced Usage

• "tỏa nhiệt hóa học": Refers specifically to an exothermic chemical reaction.

  • Sự đốt cháy là một quá trình tỏa nhiệt hóa học điển hình. (Combustion is a typical exothermic chemical process.)

• "năng suất tỏa nhiệt": A technical term meaning "calorific value" or "heat of combustion."

  • Than đá có năng suất tỏa nhiệt cao. (Coal has a high calorific value.)

Variants and Related Words

• Tỏa (v): to radiate, to emanate, to diffuse (used with other nouns like "tỏa sáng" - to shine, "tỏa hương" - to emit fragrance).
• Nhiệt (n): heat.
• Phản ứng tỏa nhiệt (n phr): exothermic reaction.
• Vật tỏa nhiệt (n phr): heat-emitting object; radiator.

Synonyms

• Emit heat: To give off heat.
• Radiate heat: To send out heat in rays or waves.
• Give off heat: A more general term for releasing thermal energy.
