Question 3 • *26-27 CFISD TX-Chemistry A CR

Which procedure could a student use to examine an intensive property of a rectangular block of wood?

Answer
A
Find the mass.
B
Record the length.
C
Measure the volume.
D
Determine the density.

Explanation

An intensive property does not depend on the amount or size of a sample. Density is intensive because it is the mass per unit volume and stays the same for a uniform piece of wood, even if the block is cut smaller. Mass, length, and volume depend on the block’s size, so determining density is the correct procedure.
