  1. 理想氣體方程式

  2. 因此,氣體的體積V∝ 乘上一個比例常數R後,可寫成等式V = R‧ 亦即 PV = nRT 理想氣體方程式 壓力(P)、絕對溫度(T)與莫耳數(n)對氣體體積(V)的影響

  3. R= ≒0.082 atm-L/mol-K 理想氣體方程式 理想氣體常數R = 0.082 atm-L/mol-K 實驗得知壓力1atm,溫度0℃時,一莫耳的氣體的體積約為22.4公升。 將其代入 PV = nRT,則可得理想氣體常數R = 0.082 壓力(P)=1atm;莫耳數(n)=1mol 絕對溫度(T)=273K ;體積(V)=22.4L 1‧22.4=1‧R‧273

  4. 理想氣體方程式 理想氣體方程式的應用 假設氣體質量為w,氣體分子量為M,則氣體莫耳數 n = 則理想氣體方程式PV =nRT,轉變為PV = ( ) RT 這是理想氣體方程式的第二種型式。 已知 為氣體的密度(ρ) 理想氣體方程式PV = ( ) RT,可以改寫成PM = ( )RT =ρRT 因此 PM =ρRT是理想氣體方程式的第三種型式。
