DA LI ZRAK
ZAUZIMA
PRSTOR,
(ZAPREMINU)?
Šta je zrak? - Zrak je smjesa
plinova koji tvore
Zemljinu atmosferu.
- Jedan je od
osnovnih životnih
uslova.
Od čega se zrak
sastoji?
- Zrak se sastoji od:
- 78% dušik
- 20,9% kisik
- 0,9% argon
- 0,03% ugljen-dioksid
ZRAK SE SASTOJI OD
Dušik Kisik Argon Ugljen-dioksid
ŠTA JE
ZAPREMINA?
Zapremina ili volumen je određeni dio prostora
koji zauzima neko
.
DA LI ZRAK ZAUZIMA
PROSTOR?
Pretpostavka: - Mi mislimo da zrak
zauzima prostor jer
kesice čipsa budu
napuhane a nisu
pune i pola je zrak a
pola čips tako da
zrak zauzima
prostor.
Na internetu smo našli eksperiment jedne djevojčice
koja je sa flašom, plastelinom, lijevkom i vodom
pokušala da sazna da li zrak zauzima prostor.
Na bocu ćemo staviti lijevak i omotati ga plastelinom.
Prvo ćemo uliti vodu u bocu a zatim ćemo staviti
rupicu na plastelin pa lijevati vodu.
Naša pretpostavka: pretpostavljamo da prije nego što
probušimo rupu u plastelinu voda neće ući u bocu a
kad je probušim da će ući.
Rezultat: kad sam ulila vodu u lijevak mali dio vode je
prošao a onda se voda zaustavila i nije ulazila u
bocu. Nakon što sam probušila rupu u plastelinu voda
je odmah ušla u bocu jer je zrak koji je zauzimao
prostor izašao van.
HVALA NA PAŽNJI!
