The discrepancies can be ascribed to the neglect of variation of the vapor pressure of curved surface to plain surface with temperature, and the misusing of Kelvin equation for small bubble during boiling. The way to reduce the discrepancy is introduced while the applicability of Kelvin equation is discussed.","PeriodicalId":23447,"journal":{"name":"University Chemistry","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70221520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to prevent the infection caused by crowd, “Suspended classes but not stop teaching and learning” was proposed by the Ministry of Education. Students in local colleges and universities show obvious variations in self-discipline, consciousness and initiative. Such a practical situation brings us a great challenge to effectively carry out the online teaching for chemistry major. Taking the online teaching of “Materials Chemistry” as an example, this paper introduces the process of online teaching of chemistry major in the local universities. In view of the problems encountered in the teaching process and the solutions adopted, this paper summarizes the issues needing attention during the online teaching. It is hoped that this paper can provide some useful reference for the online teaching of chemistry major in local colleges and universities.","PeriodicalId":23447,"journal":{"name":"University Chemistry","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70222010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It plays a critical role in fundamental chemistry courses. This paper proposed a view of three periods on the development of electronegativity. The process of deepening and gradually developing in understanding of electronegativity scale is briefly described. On the basis of a brief description of different electronegativity scales, the difference between absolute electronegativity scale, Pauling type electronegativity scale, Allen electronegativity scale and its modified Rahm electronegativity scale were discussed emphatically. The re-discussion is undoubtedly helpful for the in-depth understanding about the concept of electronegativity and the reform of teaching contents in fundamental studies.","PeriodicalId":23447,"journal":{"name":"University Chemistry","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70215102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
