關(guān)于pv=zrt是什么公式?，pv nrt是什么公式這個(gè)問題很多朋友還不知道，今天小六來為大家解答以上的問題，現(xiàn)在讓我們一起來看看吧！
1、理想氣體狀態(tài)方程(ideal gas，equation of state of)，也稱理想氣體定律或克拉佩龍方程，描述理想氣體狀態(tài)變化規(guī)律的方程。
2、質(zhì)量為m，摩爾質(zhì)量為M的理想氣體，其狀態(tài)參量壓強(qiáng)p、體積V和絕對溫度T之間的函數(shù)關(guān)系為pV=mRT/M=nRT 式中M和n分別是理想氣體的摩爾質(zhì)量和物質(zhì)的量;R是氣體常量。
3、對于混合理想氣體，其壓強(qiáng)p是各組成部分的分壓強(qiáng)p p2、……之和，故 pV=( p1+ p2+……)V=(n1+n2+……)RT，式中nn2、……是各組成部分的摩爾數(shù)。
4、 以上兩式是理想氣體和混合理想氣體的狀態(tài)方程，可由理想氣體嚴(yán)格遵循的氣體實(shí)驗(yàn)定律得出，也可根據(jù)理想氣體的微觀模型，由氣體動理論導(dǎo)出。
5、在壓強(qiáng)為幾個(gè)大氣壓以下時(shí)，各種實(shí)際氣體近似遵循理想氣體狀態(tài)方程，壓強(qiáng)越低，符合越好，在壓強(qiáng)趨于零的極限下，嚴(yán)格遵循。
6、The Ideal Gas Law ( PV = nRT ) is unlike the other gas laws in that it does not require an initial and a final state, that is it does not require the situation to CHANGE in order to determine a value for Pressure, Volume, amount of gas or Temperature.PV = nRTWhere R = 0.082 atm*L/mole*KWe can determine the Pressure, Volume, Temperature or amount of a gas (n) when the others are known. For this we must use Pressure in atmospheres, Volume in Liters, amount of gas in moles and Temperature in Kelvin.If you know the pressure, temperature and volume of a gas you can determine the number of moles.Pressure = 1.4 atmVolume = 500ml -> convert to Liters -> 0.5 LTemperature = 20 degrees Celsius -> convert to Kelvin -> 293KWhich gives us:PV = nRT (1.4 atm)(0.5 L) = (n)(0.082 atm*L/mole*K)(293K) n = 0.029 moles --------------------------------------------------------------------------------At S.T.P.In order to standardize research and results scientists use a Standard Temperature and PressureThe Temperature and Pressure are 273K and 1 Atm.If we plug those number in the equation with a quantity of 1 mole we get the volume of a mole of ANY GAS:PV = nRT (1 atm)( V ) = (1 mole)(0.082 atm*L/mole*K)(273K) V = 22.4 L The volume of ANY GAS at S.T.P. is 22.4 Liters.。
