Question

Use the particle model of matter to explain why smell of cooking can drift from the kitchhen to the living room even when there is no wind

Answer 1

Answer:

hot particles diffuse faster and more efficiently than colder particles, so as the smell of cooking is considered as 'hot particle', it diffuses to a larger area

Answer 2

the air particles having the aroma of the cooked food are hot i.e. they have high temperature due to which the particles start moving and pass the vibrations of their particles to the surrounding air particles and spread kinetic energy.
