Fizika kvíz: elmerülnek vagy lebegnek a tárgyak? Csak a zseniknek megy mind!

2021.12.18.2021.12.18. Adam

Az alábbi fizika kvízben azt próbáljuk meg felmérni, hogy mennyire emlékszel a folyadékok sűrűségére, és a felhajtó erőre. Bizony, a látszólag egyszerű kérdésekben azért sok fizikai tétel összejön 🙂

Egyszerű példákat hoztunk, bár nem biztos, hogy teljesen életszerű.

Hirdetés

Egy pohárban van 1/3 víz, mi lesz ha 1/3 szirupot töltünk hozzá?

összekeverednek

szirup a víz alá süllyed

szirup lebeg a vízen

Helyes! Helytelen!

Ugyanebbe a pohárba beletöltünk még 1/3 olajat is. Mi fog történni?

az olaj lesüllyed a szirup alá

az olaj a víz felett lesz

a víz és a szirup közzé kerül az olaj

Helyes! Helytelen!

Mi lesz, ha beleejtesz még egy kulcsot is?

lesüllyed a legaljára

a szirup tetején lebeg

az olaj és a víz között lebeg

Helyes! Helytelen!

Hirdetés

Mi történik a beleejtett száraz tésztával?

a víz tetején lebeg

szirup tetején lebeg

az olaj tetején lebeg

Helyes! Helytelen!

Mi lesz a beleejtett málna szemmel?

a szirup tetején lebeg

az olaj tetején lebeg

a víz réteg tetején lebeg

Helyes! Helytelen!

Mi lesz a belejtett gumikacsával?

a víz tetején lebeg

az olaj tetején lebeg

a szirup tetején lebeg

Helyes! Helytelen!

Hirdetés

Ha összekeverjük az egészet, és állni hagyjuk pár órát, akkor mi történik?

Az olaj visszaáll a tetejére, viszont a szirup összekeveredik a vízzel.

visszaállnak a rétegek és a tárgyak az eredeti helyükre

a szirup, a víz és az olaj is összekeveredik, a tárgyak pedig az egész tetején lebegnek

Helyes! Helytelen!

Fizika kvíz: elmerülnek vagy lebegnek a tárgyak? Csak a zseniknek megy mind!
