P/Pa
V/m3
PV/Pa?m3
(p+av2)(v-b)/Pa?m3
1.013×105
2.24×10-2
2.3×103
2.3×103
1.013×107
2.24×10-4
2.3×103
2.3×103
5.065×107
0.62×10-4
3.1×103
2.3×103
1.013×108
0.46×10-4
4.1×103
2.3×103(1)由上述实验数据可以得到如下公式: =K (K为常数),其中K= (写上单位).由数据形式变为公式形式运用了 法.(2)在压强由1.013×105Pa增加到1.013×107Pa的过程中,我们可以将公式简化为 ,则这时的p-V关系可以用图象中的图线 来表示.(3)实验中若氮气的压强为1.013×106Pa,则它的体积为 .
