Find out liquids of viscocity greater and lower than that of water and tabulate them.

Density of ice is lower than that of water.

Write examples for liquids of density greater and lesser than that of water.

Classify the following liquids into liquids having density greater than that of water and liquids having density less than that of water. Honey,kerosene,glycerine,mercury,saline water,petrol,diesel

Suppose the hydrometer is dipped in a liquid of density greater than that of water. Will the liquid surface be above or below the marking of 1?

Account for the following observations: i) The density of ice is lower than that of water. ii) Hard water doesn't give ready lather with soap.

A car and a truck have the same kinetic energies at a certain instant while they are moving along two parallel roads . (Assume that the truck is heavier than the car). If the mass of the truck is 100 times greater than that of the car ,find the ratio between their velocities.
