Question

A piece of solid quartz having a density of 2.7 g/cm3 is placed on the surface of liquid W. When the quartz is released, it will pass through:
A) W and X, but not Y or Z B) W, X, Y, and Z
C) W, but not X, Y, or Z D) W, X, and Y, but not Z

Answer 1

This is the attachment

Answer 2

moved to Physics

major hint: if an object is less dense than the surrounding liquid, it will float
if an object is more dense than the surrounding liquid, it will sink

so since your object has density 2.7 g/cm^3, it will pass through any liquid less dense than 2.7 but not through anything greater than 2.7

Answer 3

so C then right?

Answer 4

mabye

Answer 5

wym?

Answer 6

Not quite, give it one more go

Remember, it will pass through *every* layer less than 2.7 g/cm3 in density

Answer 7

D?

Answer 8

Im not sure how its not c because 0 is less than 2.7 and 8 is greater than 2.7

Answer 9

Make sure you’re looking at the whole #

Layer W density = 1.0
X = 1.8
Y = 2.3
Z = 3.0

Therefore it will pass through W X Y and not Z (therefore choice D is correct)

Answer 10

OOOHHH thank you soooo much
