One of the universal constants introduced by the Austrian physicist Boltzmann. If the pressure of 1 mole of ideal gas is p , its volume is V , and its absolute temperature is T , then the equation of state pV = RT holds between these. The proportionality constant R is called the gas constant, and when this is divided by Avogadro's number (number of moles) N A , k = R / N A = 1.380658 x 10 -23 J・K -1 [Koide Shoichiro] [References] | | | | | |Source: Shogakukan Encyclopedia Nipponica About Encyclopedia Nipponica Information | Legend |
オーストリアの物理学者ボルツマンの導入した普遍定数の一つ。理想気体1モルの圧力をp、体積をV、絶対温度をTとすると、これらの間には状態方程式pV=RTが成り立つ。比例定数Rは気体定数とよばれるが、これをアボガドロ数(モル分子数)NAで割ったもの [小出昭一郎] [参照項目] | | | | | |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
