Question

Explain the following with the help of activities..

1) Sublimation of Ammonium chloride/camphor.

2)Particles of matter are very small.

3)Particles of matter attract each other.

4)Particles of matter have space between them.​

Answer 1

Answer:

1. For that, you use odonil in your bathroom, that's an example of sublimation as it has Camphor

or Naphthalene balls you put in the hand wash area, in stalls, etc

2. Try to see a dust particle when you open the window of your room (sunlight should be there)

It is based on Brownian motion where particles move, we also see that particles are small too!

3. Try to cut the stream of water with your fingers (use taps). you may notice they attract each other, hence, you can't cut the stream of water

4. Mix salt in water, you notice that the salt disappears and the level of water didn't rise, meaning that the salt particles got space in between the water molecules, hence proving that particles of matter hve space between them
