1) Which property of an object allows it to bend?
    A.  color
    B.  flexibility
    C.  mass
    D. size

Color, mass - which is the amount of matter there is in an object, and size have nothing to do with an objects ability to bend.  Flexibility, however is the ability to bend.

Observing Details


Base your answers to the next two questions on the diagram below and on
your knowledge of science. The diagram shows four identical marbles and a
graduated cylinder containing 43 mL of water.

A student puts two marbles in the cylinder and the water level rises
from 43 mL to 45 mL. The student then puts the other two marbles in
the graduated cylinder. What will the water level be when all four
marbles are in the graduated cylinder?
A 43 mL
B 45 mL
C 47 mL
D49 mL

Graduated Cylinder - Marbles


Which property of the marbles causes the water level to rise when they
are put in the graduated cylinder?

B shape
C texture
D volume

Displacement
