calorimeter
Meaning: A scientific instrument used to measure the amount of heat involved in a chemical reaction, physical change, or heat capacity of a substance.
Calorimeters are essential in thermodynamics, food science, and materials testing. In academic contexts, bomb calorimeters measure the energy content of fuels and foodstuffs, while differential scanning calorimeters analyse phase transitions in materials. The term rarely appears outside scientific and technical writing, though it surfaces occasionally in discussions of nutrition when explaining how the calorie content of food is determined.
Examples
- The bomb calorimeter revealed that the new biofuel yielded significantly more energy per gram than its predecessor. 弹式量热计显示,这种新型生物燃料每克产生的能量远高于其前代产品。El calorímetro de bomba reveló que el nuevo biocombustible proporcionaba significativamente más energía por gramo que su predecesor.ボンベ熱量計により、新しいバイオ燃料が前世代製品よりもグラムあたり著しく多くのエネルギーを生み出すことが明らかになった。봄베 열량계를 통해 새로운 바이오 연료가 기존 제품보다 그램당 훨씬 더 많은 에너지를 생산한다는 사실이 밝혀졌다.
- Students were asked to use a calorimeter to determine the specific heat capacity of copper in their practical examination. 学生们被要求在实践考试中使用量热计测定铜的比热容。Se pidió a los estudiantes que utilizasen un calorímetro para determinar la capacidad calorífica específica del cobre en su examen práctico.学生たちは実技試験で熱量計を使用して銅の比熱容量を測定するよう求められた。학생들은 실기 시험에서 열량계를 사용하여 구리의 비열용량을 측정하도록 요구받았다.
- Pharmaceutical researchers relied on a differential scanning calorimeter to study the stability of the drug compound under varying temperatures. 制药研究人员依靠差示扫描量热计来研究药物化合物在不同温度下的稳定性。Los investigadores farmacéuticos recurrieron a un calorímetro diferencial de barrido para estudiar la estabilidad del compuesto farmacológico a distintas temperaturas.製薬研究者たちは示差走査熱量計を用いて、さまざまな温度条件下における薬物化合物の安定性を調べた。제약 연구자들은 시차주사 열량계를 이용하여 다양한 온도 조건에서 약물 화합물의 안정성을 연구했다.
