okie:)

michele_laino · Answer

experimentally, speaking, I say solid Iron

anonymous · Answer

okay, so choice C? is it because it's solid as opposed to gas/liquid?

anonymous · Answer

therefore it is not as dispersed? allowing faster sound movement?

michele_laino · Answer

from my table, I read:
iron---> v=5,000 m/sec
alcohol---> v=1,220 m/sec
helium, I think is like hydrogen---v=1,269 m/sec
