从气压计上读得当地大气压力是765mmHg,试换成“Pa”“标准大气压”和“mmH2O”。
正确答案:
解:∵1mmHg=133.322Pa
∴765mmHg=101991.33Pa
又760mmHg=1标准大气压故765mmHg=1.007标准大气压
又1mmH2O=9.81Pa故1mmHg=13.6mmH2O故765mmHg=10404mmH2O
答:765mmHg相当于101991.33Pa,1.007标准大气压,10404mmH2O。
∴765mmHg=101991.33Pa
又760mmHg=1标准大气压故765mmHg=1.007标准大气压
又1mmH2O=9.81Pa故1mmHg=13.6mmH2O故765mmHg=10404mmH2O
答:765mmHg相当于101991.33Pa,1.007标准大气压,10404mmH2O。
