Question 9

A technician measures the pressure due to the liquid column at the same vertical depth in two unidentified liquid samples. The pressure readings are shown in the table.

SamplePressure due to the liquid column
K18 000 Pa18\,000\ \text{Pa}18000 Pa
L12 000 Pa12\,000\ \text{Pa}12000 Pa

Which conclusion is correct?

[1]
A

The samples have the same density because the measurements are at the same depth

B

The densities cannot be compared unless their density values are given

C

Sample L is denser than sample K

D

Sample K is denser than sample L
