nhiệt lí

Definition

1. Noun (Physics):
   • Thermograph: An instrument that automatically records temperature variations over time, producing a continuous graphical record called a thermogram.

Usage Examples

• Noun:
  • Nhà khoa học sử dụng nhiệt lí để theo dõi sự thay đổi nhiệt độ trong thí nghiệm. (The scientist uses a thermograph to monitor temperature changes in the experiment.)
  • Đường cong trên nhiệt lí cho thấy nhiệt độ tăng đột ngột vào ban ngày. (The curve on the thermograph shows a sudden temperature increase during the day.)

Advanced Usage

• The term "nhiệt lí" is a specialized scientific term. In modern technical contexts, the English loanword "thermograph" or the related term "temperature recorder" is often used directly.

Variants and Related Words

• Nhiệt kế (n): Thermometer. An instrument for measuring temperature, but typically does not record data automatically.
  • Nhiệt kế chỉ cho biết nhiệt độ tại một thời điểm. (A thermometer only shows the temperature at a specific moment.)
• Nhiệt ký (n): Alternative, less common spelling for "nhiệt lí" (thermograph).

Synonyms

• Temperature recorder: A device that records temperature.
• Thermometer: A device that measures temperature (a broader category that includes non-recording types).

Notes on Usage

• "Nhiệt lí" is a technical term derived from Sino-Vietnamese roots ("nhiệt" = heat, "lí" = record). It is not commonly used in everyday conversation but is found in scientific, meteorological, or industrial contexts.
• It is important not to confuse "nhiệt lí" (thermograph) with "nhiệt lực" (thermal force/energy) or "nhiệt học" (thermodynamics).
