From the given table of densities of different substances, infer whether the given object would float or sink in the given solution?
 
Material Density g/cm3
Gasoline 0.7
Gold 19.3
Lead 11.3
Mercury 13.6
Paraffin (wax) 0.87
Platinum 214

Find:
(i) Will a bar of gold sink in mercury?
(ii) Will a piece of platinum float on gasoline?
(iii) Will a block of paraffin sink in gasoline?
(iv) Will a piece of platinum sink in mercury?

Dear Student ,
(i) Gold bar will sink in mercury , density of gold is greater than the density of mercury .
(ii) Piece of platinum will sink in the gasoline as the density of platinum is greater than the density of gasoline .
(iii) Block of paraffin will sink in gasoline .
(iv) Piece of platinum will sink in mercury .

Regards
