Question

Describe a simple activity to show the random motion of particles of matter​

Answer 1

Answer:

beaker and leave them undisturbed. After sometime it can be observed that the colour of the ink spreads evenly throughout the water and also the honey in the second beaker. This happens because the molecules continuously keep on moving. When temperature is increased, the movement of particles become faster.

Answer 2

Take two beakers filled with water, put a drop of red ink in one beaker and honey in the second

beaker and leave them undisturbed. After sometime it can be observed that the colour of the ink spreads evenly throughout the water and also the honey in the second beaker. This happens because the molecules continuously keep on moving. When temperature is increased, the movement of particles become faster. This is due to increase in their kinetic energy.

(i) Oxygen has neither fixed volume nor fixed shape.

(ii) Oxygen exerts pressure due to collision of the molecules on the walls of containing vessel and among themselves.
