Answer

Explanation:

Step1: Recall density - sinking and floating principle

An object sinks in a fluid if its density ($\rho_{object}$) is greater than the density of the fluid ($\rho_{fluid}$), and floats if $\rho_{object}<\rho_{fluid}$.

Step2: Compare quartz density with liquid densities

The density of the solid quartz is $\rho_{quartz}=2.7\ g/cm^{3}$. The density of liquid $W$ is $\rho_{W} = 1.0\ g/cm^{3}$, the density of liquid $X$ is $\rho_{X}=1.8\ g/cm^{3}$, the density of liquid $Y$ is $\rho_{Y}=2.3\ g/cm^{3}$, and the density of liquid $Z$ is $\rho_{Z}=3.0\ g/cm^{3}$. Since $\rho_{quartz}>\rho_{W}$, $\rho_{quartz}>\rho_{X}$, and $\rho_{quartz}>\rho_{Y}$, but $\rho_{quartz}<\rho_{Z}$, the quartz will pass through $W$, $X$, and $Y$ but not through $Z$.

Answer:

C. $W$, $X$, and $Y$, but not $Z$
