Question

what is one way to separate a mixture?

what is the difference between mass and volume?

mia has a wallet. it has a mass of 15g and a volume of 5mc3. what is the density of the wallet?

if you increase the gravity on the moon, what would happen to the weight of an astronaut?

(pleassee hurry! i have a test i need to finish !)

Answer 1

1. Substances in a mixture can be separated using different methods, for example distillation (separation of two liquids).
2. Mass is the amount of matter an object contains.
Volume is the amount of space occupied by a three-dimensional object.
3. d(wallet) = 15g÷5cm³ = 3g/cm³.
4. Weight of an astronaut also increases. W=m·g.
