p silver = 10500 kg \ m ^ 3, p zinc = 7100 kg \ m ^ 3, which means that the density of zinc is less than that of silver.
p of concrete = 2300 kg \ m ^ 3, p of marble = 2700 kg \ m ^ 3, which means p of marble is more than p of concrete.
p of gasoline = 710 kg \ m ^ 3, p of alcohol = 800 kg \ m ^ 3, which means p of gasoline is less than p of alcohol.
