Question

describe sendimationand decantation .What kind of a solid change with a rise in temperature​

Answer 1

Sedimentation

The process of settling down of particles of a solid in a liquid is known as sedimentation.

Decantation

Decantation is a process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension.

As temperature rises, the kinetic energy of the molecules within the solid begin to vibrate, which decreases the attraction of these molecules. There is a temperature threshold, referred to as the melting point, at which the vibration becomes sufficient enough to cause the solid to change to liquid.

Answer 2

Explanation:

SEDIMENTATION

Sedimentation is defined as the separation process in which solids are separated from the liquid. All the solids settle down at the bottom of a beaker and on top, a clear layer of liquid is obtained.

DECANTATION

Decantation is defined as the separation process in which two immiscible liquids are separated. This is done by pouring out the clear upper layer of liquid. Separation of a mixture of oil from water is an example of decantation.
