Question

solve the question pls ​

Answer 1

Explanation:

1. Due to sublimation.

2Due to diffusion

Answer 2

Napthalene balls sublime

Sublimation is a process in which the solid directly changes into gas without undergoing liquid state

Hence napthalene disappears with time without leaving any solid

2)when the perfume is released it changes into vapor .

This process is fast due to which the kinetic energy of the molecules is high and the rate of diffusion too

Hence we can get.the smell of a perfume sitting several meters away
