Q

Densitet

A

är täthet som avser massan på en viss volym. (Massa/volym)

39
Q

Arkimedes princip

A

Kan beskriva/förklara varför den som har lägre eller högre densitet lägger sig överst respektive underst.

Frigolit exempelvis har en stor volym jämfört med sin massa och har därför en väldigt låg densitet.
