Ka'idar motsa jiki ta iskar gas

Ka'idar motsi ta iskar gas ta bayyana cewa kowace abu tana ƙunshe da ƙwayoyin atom ko molecules, kuma waɗannan ƙwayoyin atom ko molecules suna cikin motsi mai ci gaba da bazuwar. Wannan hasashe na ka'idar motsi ya dace da yanayi da yanayin ƙwayoyin atom ko molecules da suka samar da iskar gas. Ƙarfin jan hankali tsakanin ƙwayoyin atom ko molecules da suka samar da iskar gas yana da rauni sosai, yana ba da damar ƙwayoyin atom ko molecules su motsa cikin 'yanci.

Lokacin motsi, ƙwayoyin halitta ko ƙwayoyin halitta suna da saurin gudu. Kwayoyin halitta ko ƙwayoyin halitta suma suna da nauyi. Saboda suna da taro (m) da sauri (v), ƙwayoyin halitta ko ƙwayoyin halitta suna da kuzarin motsi (EK) da motsi (p). Ƙarfin motsi : EK = 1⁄2 mv 2. Yayin da motsi : p = m v. Baya ga kuzarin motsi da motsi, akwai kuma ƙarfi (F). Lokacin motsi cikin 'yanci, karo yana faruwa. Don haka ƙarfi yana tasowa saboda canjin motsi lokacin da karo ya faru.
