Question

A block of material with a density of 0.90 g/cm® is dropped first into water ana then into gasoline (density 0.69 g/cm3). The block will Select one: O a. float in both O b. float in water but sink in gasoline O c. depends on its total mass O d. sink in both O e. sink in water but float in gasoline

Answer 1

here,

the density of material , p = 0.9 g/cm^3

the density of water , pw = 1 g/cm^3

as pw > p

the block will float in water

the density of gasoline , pg = 0.69 g/cm^3

as pg < p

the block will not float in gasoline

the correct option is b) float in water but sink in gasoline
