Liquids have high density due to their molecules are tightly packed in a small volume.

Liquids have no definite volume.

Assertion (A) Liquids tend to have maximum number of molecules at their surface. Reason (R) Small liquid drops have spherical shape.

Explain why solids have high density.

Why liquids have a definite volume but no definite shape?

Why liquids have a definite volume but no definite shape?

Define density. What does it tell you in terms of how the molecules are packed?

Statement -1: High density polythene is form when addittion polymerisation of ethene takes place in a hydrocarbon solvent in the presence of a catalyst Ziegler-Natta catalyst at a temperature of 333k to 343k and under a pressure of 6-7 atmosphere. Statement -2: High density polythene consists of linear molecules and has a high density due to closed packing and it is used for manufacturing buckets, dustbins, bottles. select correct option regarding these statements.

Assertion : Viscosity of liquids decreases as the temperature rises . Reason : At high temperature , molecules have high kinetic energy and can overcome the intermolecular forces to flow faster .

Choose the correct option to fill in the blank If more mass is packed into the same volume. Then density is ……… (more/less)

A body P floats in water with half its volume immersed. Another body Q floats in a liquid of density (3)/(4) th of the density of water with two - third of the volume immersed. The ratio of density of P to that of Q is
