Question

Two beakers A and B containing hot and cold water respectively are taken. A drop of ink is added in both.

a) Perform this activity to find out in which beaker is the uniform colour obtained faster?

Answer 1

Answer:

in hat water it more faster

Answer 2

Activity to find out dispersion of ink in water

Explanation:

• There are two beakers labelled as A and B.
• Beaker A is filled with specific volume of hot water.
• Beaker B is filled with cold water of same volume.
• A unit drop of ink is added in both beakers A and B simultaneously. Following events take place:
• In beaker A, the ink is dispersed very fast and a uniform color is obtained.
• In beaker B, ink is dispersed at a slower rate than beaker A, uniform color is achieved after some time.
• This complete activity can be explained on the basis of kinetic energy of water molecules.
• Beaker A has water of higher temperature. This causes enhanced kinetic energy of molecules. Molecules having higher energy show more motion and thus greater distribution of ink.
