Question

Give reason for the given observations. We can get the smell of perfume sitting several metres away.

Answer 1

we can get the smell of perfume sitting several meters because they shows the process of diffusion so they diffuse from higher concentration to lower concentration and the smell diffuses into air.

Answer 2

Dear Student,

In on word I'd say diffusion.

◆ We can get the smell of perfume sitting several metres away because -

• Diffusion of gases through air depends upon kinetic energy possesed by the gas.
• Particles of perfume are aromatic liquids and high kinetic energy.
• Thus these get easily transported several metres in the surrounding.
• When particles of perfume reach our nostrils, we get the sense of smell.

Thanks dear...
