This anomalous expansion of water is an abnormal property of water whereby it expands instead of contracting when the temperature goes from 4°C to 0°C, and it becomes less dense. The density becomes less as it freezes because molecules of water normally form open crystal structures when in solid form.

the property of substance by which it regains its shape nd size aftr removal of deforming force ,is called elasticity nd..which cant regain , is called plasticity

1Thank You

Ananya Chaturvedi 5 years, 8 months ago

After the removal of deforming force the body comes back into its previous state or shape that body is known as plastic body.And this property is known as plasticity,e.g. rubber band. After the removal of deforming force the body does not come back into its previous state or shape that body is known as elastic body.And this property is known as elasticity.

Mr. Badmash 5 years, 8 months ago

An ideal fluid (also called Perfect Fluid) is one that is incompressible and has no viscosity. Ideal fluids do not actually exist, but sometimes it is useful to consider what would happen to an ideal fluid in a particular fluid flow problem in order to simplify the problem.
