It is easier to crush a capped bottle filled with water than an empty bottle because liquids are compressible.
An empty plastic bottle floats, while a plastic bottle filled with sand sinks in water because
The mass of an empty density bottle is 21.8 when filled completely with water it is 41.8 g and when filled completely with liquid it 40.6 g . Find :
(a) the volume of density bottle.
(b)the relative density of liquid.
A density bottle weighs 20.25g when empty, 40.75g when filled with a liquid and 50.25g when filled with water. Find (a) Volume of the bottle ; (b) Density of the liquid.
