Three identical containers were filled with 100 ml of Substance X, Y, and Z. X took the shape of the container but did not fill it. Y filled the entire container. Z remained as a cube at the bottom. What are the states of X, Y, and Z?

A X: Gas, Y: Liquid, Z: Solid
B X: Solid, Y: Liquid, Z: Gas
C X: Liquid, Y: Solid, Z: Gas
D X: Liquid, Y: Gas, Z: Solid

Worked Solution

Step 1: X (takes shape, doesn't fill) = Liquid. Step [2-9]: Y (fills entire container) = Gas. Step [2-9]: Z (fixed shape/cube) = Solid.

Correct answer: X: Liquid, Y: Gas, Z: Solid
