LIST OF PRACTICALS

1. To determine the density of a solid (denser than water) by using spring balance and a measuring cylinder.

2. To establish the relation between loss in weight of a solid when fully immersed in (i) tap water (ii) strongly salty water, with weight of water displaced by it taking at least two different solids.

3. To Calculate the pressure exerted by a wooden block on sand.
