A.Theroot-mean-squarespeedofthegasmoleculesdoubles.
B.Theaverangekineticenergyofthegasmoleculesincreasesbyafactorof√2(根号2).
C.Theaverangekineticenergyofthegasmoleculesincreasesbyafactorof4
D.Thespeedsofthegasmoleculescoverawiderang,buttheroot-mean-squarespeedincreasbyafactorof√2(根号2).
E.Thespeedsofthegasmoleculescoverawiderang,buttheroot-mean-squarespeedincreasbyafactorof2.
貌似有关于理想气体,但是这个用什么公式算?
另外这个Theroot-mean-squarespeedofthegasmolecules
