Description
Известные опыты дл дe ioнcтpaции зависимости температуры Knniiни жидкости, например при noiniжепном давлепии, в oripoKiniyTOii и охлаждаемой колбе или с откачива )пшм воздуха и пара над испарлющейс жидкостью пе вл ютс достаточно нагл дными и безопасными.Known experiments for the dependence of the temperature of liquid on liquid, for example, under pressure, in oripoKiniyTOii and in a cooled flask or pumped out of air and steam over evaporating liquid, are sufficiently smooth and safe.
В частности, при проведении таких опытов создаетс впечатлсиие проиикповепи воздуха в колбу.In particular, when such experiments are carried out, the flow of air into the flask is impressed.
