Question

D. COMPLETE THE FOLLOWING TABLE : LIGHTER (upper) DENSER (lower) S.No. EXAMPLES 1. Oil + water 2. Chloroform + water 3. Mercury + water 4. Benzene + water​

Answer 1

1. Oil + water 2. Chloroform + water 3. Mercury + water 4. Benzene + water

Answer 2

◊ Density is defined as the mass per unit volume

◊ Substances having more density is termed as denser substances

◊ Substances having less density is termed as lighter or rarer substances

◊ Also, denser substances will sink down and rarer substances will float over the denser substances

1) Water is denser than oil

Hence, Oil will float over water

2) Chloroform is denser than water

Hence, Water will float over chloroform

3) Mercury is denser than water

Hence, Water will float over mercury

4) Water is denser than benzene

Hence, Benzene will float over water
