Science 1. A student was asked to compare the masses of four blocks that were all the same size but made of different materials. The student used a balance to
compare the masses of two blocks at a time. The student repeated this process three more times with different pairs of blocks and recorded
observations.
***
Which list shows the blocks in order from greatest to least mass?
O A P, M,L, N
B. N, L, M, P
OC. L, NMP
OD. P, M, N, L
