Question

When an incense stick is lighted in one corner of a room, its fragrance spreads in the whole roon quickly. Which charachteristic of particles of matter is illustrated by this observation?

Answer 1

The incense stick releases the gas when it is lighted in one corner of the room . The molecules in the gas are in free state. There are large intermolecular spaces between the molecules of the gas. The gases are not rigid , they don't have definite shape . That's why they spread very quickly . Hence , the fragrance spreads in the whole room very quickly

Answer 2

here is the answer:-

charachteristic of particles of matter illustrated by this observation is that particles of matter are always moving. When an incense stick is lighted in one corner of a room, its fragrance spreads in the whole roon quickly because the particles were mixes with the space present in the air and as the air moves the particles also move and room is full of fragrance.
