The volume of the yellow object is not 29cm3 and it is also not 57.4cm3. The white object has a greater mass than the pink object. The gray object has a density of 1.349 grams per cubic cm and a mass of 76.9g.
The density of water is 1.0 grams per cubic cm. If the white object was placed in water, it would sink.
The density of water is 1.0 g/cm3. If the yellow object was placed in water, it would float.
The density of aluminum is 2.7 g/cm3. The violet object is more dense than aluminum
One object has a volume of 57.4 cm3 and a density of 0.5 grams per cubic centimeter.
The volume of the violet object is not 11.6 cubic centimeters

it would be a gas formation

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
