sari is studying four different samples of materials. this table shows the mass and volume of the samples.

a 2-column table with 4 rows. the first column labeled sample with entries w, x, y, z. the second column labeled measurements with entries no definite shape no definite volume, no definite shape definite volume, no definite shape no definite volume, definite shape definite volume.

which sample material(s) could be liquid?
w and y
x
x, w, and y
z

X: Liquid

Explanation:

As we know that there are 3 states of matter :

Solid state : It is a state in which the particles are closely packed and does not have any space between them. This state have a definite shape and volume.

Thus sample Z is solid.

Liquid state : It is a state in which the particles are present in random and irregular pattern. The particles are closely arranged but they can move from one place to another. This state have a definite volume but does not have a fixed shape.

Thus sample X is liquid.

Gaseous state : It is a state in which the particles are loosely arranged and have a lot of space between them. This state have indefinite volume as well as shape. Thus samples W and Y are gases.

Thus sample X is liquid

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
