Standard conditions
标准条件
Defined conditions for measuring and comparing chemical properties, usually 298 K (25 °C) and 1 atm pressure. Standard conditions are used to define standard electrode potentials and other thermodynamic quantities.
用于测量和比较化学性质的规定条件，通常为 298 K (25 °C) 和 1 个大气压。标准条件用于定义标准电极电位和其他热力学量。(Yòng yú cè liáng hé bǐ jiào huà xué xìng zhì de guī dìng tiáo jiàn, tōng cháng wéi 298 K (25 °C) hé 1 gè dà qì yā. Biāo zhǔn tiáo jiàn yòng yú dìng yì biāo zhǔn diàn jí diàn wèi hé qí tā rè lì xué liàng.)
About the IPA
The International Phonetic Alphabet is a standardized system of symbols used to represent the sounds of spoken language.
It helps linguists, language learners, and educators accurately describe pronunciation across languages.
Example: the word "hello" in British English is transcribed as /həˈləʊ/ in IPA.
