sonia has three different sized blocks of copper . she made observations and mesaurements of each block. which of her measurements would be different ?

This question lacks options, the options are:

A.The density of each block.

B.The electrical conductivity of each block.

C.The melting point of each block.

D.The volume of each block

The answer is D. Volume of each block

Explanation:

According to this question, Sonia has three blocks of different sizes. She then made observations and measurements of each block. The physical property of a substance that depends on the size of that substance is called EXTENSIVE PROPERTIES. This include mass, height, volume, length etc.

In this case, the different measurement Sonia will record on each copper block will be the VOLUME OF EACH BLOCK. This is because the volume depends on the size of the block (extensive), hence, will have different volume measurements.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
