Kusiyana pakati pa Tyndall effect ndi Brownian motion

Kodi zotsatira za Tyndall ndi chiyani?

Mphamvu ya Tyndall ndi chinthu chowoneka bwino chomwe chimachitika pamene kuwala kwamwazika mu colloidal medium, ndiko kuti, kuyimitsidwa kwa tinthu tating'onoting'ono tamadzi kapena gasi. Kuwala kumamwazikana mbali zonse ndipo kumatulutsa kuwala kowonekera. Kuwala kowonekera kumeneku ndiko komwe kumatchedwa Tyndall effect.

Kodi brownian movement ndi chiyani?

Kusuntha kwa Brownian kumatanthauza kusuntha kwachisawawa komwe kumachitika ndi tinthu ting'onoting'ono tomwe timakhala mu colloidal medium chifukwa cha kutenthedwa kwa matenthedwe. Ndiko kuti, tinthu tating'onoting'ono timayenda mbali zonse komanso pa liwiro losiyana chifukwa cha mphamvu ya kinetic yomwe ali nayo. Kuyenda molakwika kumeneku kumadziwika kuti Brownian motion.

Kusiyana pakati pa Tyndall effect ndi Brownian motion

Ngakhale zotsatira za Tyndall ndi kayendedwe ka Brownian zimatha kuwonedwa mu colloidal media, pali kusiyana kwakukulu pakati pa zochitika zonse ziwiri.

1. Chifukwa cha zochitikazo

Zotsatira za Tyndall zimachitika chifukwa cha kubalalitsidwa cha kuwala mu colloidal sing'anga, pamene Brownian kuyenda ndi chifukwa matenthedwe mukubwadamuka wa tinthu ting'onoting'ono particles.

2. Maonekedwe owoneka

Zotsatira za Tyndall zimadziwonetsa ngati kuwala kowoneka bwino komwe kumabalalika mbali zonse, pomwe kusuntha kwa Brownian sikuwoneka bwino chifukwa tinthu tating'onoting'ono timayenda molakwika ndipo sizipanga mawonekedwe odziwika.

3. Mapulogalamu

Zotsatira za Tyndall zimakhala ndi ntchito zambiri m'malo osiyanasiyana, monga zamankhwala, sayansi yasayansi ndi sayansi. Mwachitsanzo, amagwiritsidwa ntchito pozindikira maselo a khansa komanso mawonekedwe a mapuloteni. M'malo mwake, kusuntha kwa Brownian kumagwiritsidwa ntchito makamaka mu chiphunzitso cha molekyulu ya kinetic komanso pofotokozera kufalikira kwa mamolekyu m'madzi.

pozindikira

Mwachidule, zotsatira za Tyndall ndi kusuntha kwa Brownian ndi zochitika ziwiri zosiyana zomwe zimachitika mu colloidal media ndipo zimakhala ndi zifukwa zosiyana, zowoneka ndi ntchito. Zochitika zonse ziwiri ndi zofunika kuzimvetsa njira zina m'madera osiyanasiyana a sayansi.
