You need to get really close to get to smell the unlit incense stick whereas when we light the incense stick we can get the smell even from a distance.
The reason is simple. When we light the incense stick the kinetic energy increases. Due to the increase in kinetic energy the particles vibrate more quickly. the particles of the aroma of the lit incense stick thus diffuse faster in the air and reach us far away.
