    You found the relative densities of some solids and some liquids by doin some activities. List the solids and liquids in increasing order of relative density.

    Is rubber band solid or liquid ? why?

    Give one property of a solid that a liquid does not possess.\

    The surface tension of a liquid is 80 dyne/cm. Its relative density is 0.8. If the angle of contact between the liquid and glass is 60^(@) , find the height to which the liquid rises in a glass capillary tube of radius 1 mm. (Assume g=10ms^(-2) )

    The angle of contact between glass and water is 0^(@) and it rises ina capillary upto 5 cm when its surface tension is 70 dynes/cm. Another liquid of surface tension 140 dyne/cm angle of contact 60^(@) and relative density 2 will rise in the same capillary by
