Q

what is viscosity?

A

the internal resistance/friction that keeps a fluid from flowing

17
Q

what is density?

A

mass per unit volume; it can be found by dividing mass by volume

18
Q

what is the buoyant force?

A

the upwards force that a fluid exerts onto an object; opposite of what gravity in a fluid does in an object

19
Q

what is buoyancy?

A

the tendancy of an object to float when placed in a fluid

20
Q

what are elements

A

can’t be broken down

21
Q

what are compounds?

A

two or more elements

22
Q

IMPORTANT: what is colloid?

A

an HE mixture in which the particles don’t settle, and stay mixed together

23
Q

IMPORTANT: what is emulsion?

A

when droplets of fat are prevented from joining by an emulsifying agent

24
Q

IMPORTANT: what is suspension?

A

an HE mixture in which the particles don’t settle, but eventually seperate from one another

25
Q

What is mass?

A

amount of matter in an object

26
Q

what is volume?
