vzny ve svch pevnch polohch, kolem kterch kmitaj. Kapaln skupenstv Kapaln ltka je jedno ze skupenstv ltek, pi kterm jsou stice ltky relativn blzko sebe, ale nejsou vzny v pevnch polohch a mohou

se pohybovat v celm objemu. Plynn skupenstv Plynn ltka je jedno ze skupenstv ltek, pi kterm jsou stice relativn daleko od sebe, pohybuj se v celm objemu a nepsob na sebe pitalivou silou.

Zmny skupenstv Led je pevn krystalick ltka,

nemn svj tvar. Voda je kapalina. Snadno mn svj tvar, ale jej objem se skoro nemn. Vodn pra je bezbarv prhledn plyn, snadno mn svj tvar i objem.

Sublimace a desublimace Sublimace je pemna pevn ltky na plynnou Desublimace je pemna plynn ltky na pevnou Tn a tuhnut TN - doshne-li krystalick ltka urit teploty, mn se v kapalinu. Napklad pidn soli v zim na zmrzl

led na chodnku. Tm se sn jeho teplota tn a pi okoln teplot ni ne 0 C zane tt. TUHNUT - Ochlazujeme-li kapalinu vzniklou tnm krystalick ltky, mn se pi teplot tuhnut v pevn tleso. Vypaovn a kapalnn VYPAOVN - pemna kapaliny v pru se nazv vypaovn. Kapalina se vypauje na

volnm povrchu pi kterkoliv teplot. Rzn kapaliny se pi te teplot vypauj rzn rychle. KAPALNN - obrcen dj k vypaovn je kapalnn (kondenzace). Pi tomto dji odevzdv ltka svmu okol skupensk teplo kondenzan. Var

Vypaovn probh tak dlouho, a nastane dynamick rovnovha, kdy se pry nad kapalinou stanou sytmi. Ve vtin ppad je nad povrchem kapaliny krom jejich sytch par tak vzduch, kter proces vypaovn ovlivuje. Prbh vypaovn pi dan teplot zvis na pomru napt sytch par a atmosfrickho tlaku.

Skupensk teplo tn Je teplo, kter pevnmu tlesu s teplotou tn musme dodat, aby se zmnilo na kapalinu o teplo tn. Vzorec: Lt = m lt
