Chemistry and physics equations commonly include R, the symbol for the gas constant, molar gas constant, ideal gas constant, or universal gas constant. It is a proportionality factor that relates energy scales and temperature scales in several equations. Gas Constant in Chemistry In chemistry, the ...
According to Dalton's law of partial pressures,the principle of experiment "Determination of the ideal gas constant R",the volume and pressure of hydrogen produced in the experiment were analyzed and discussed. 从道尔顿分压定律出发,对教学实验"理想气体常数R的测定"中产生的氢气的体积、分压和该实验...
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...
Why is the universal gas constant in PV = nRT represented by the letter R? Donald R. Paulson Department of Chemistry California State University Los Angeles, CA 90032 Answer This is best answered by tracing the origins of the ideal gas law itself. One of the first persons to combine Boyle...
