The gas constant is the physical constant in the equation for theIdeal Gas Law: PV = nRT P ispressure, V isvolume, n is the number ofmoles, and T istemperature. Rearranging the equation, you can solve for R: R = PV/nT The gas constant is also found inthe Nernst equationrelating the...
简谈普适气体常量R——贯穿普化教育的重要常量
Key Words: Universal gas constant; Boltzmann’s constant; Acoustic measurement 普适气体常量(universal gas constant) ,又称气体常量、理想气体常量、摩尔气体常量,多以R 表 示。这一常量在普通化学教育中有着重要的地位与独特的物理含义,许多基本等式中都出现了这一 常数,如理想气体定律(ideal gas law)、能斯...
