Give reasons for the following observation: The smell of hot sizzling food reaches you several metres away, but to get the smell from cold food you have to go close.

Answer 1

$\huge\mathbb\red{Answer- }$

$\green{Reasons:}$

⭐It is because the kinetic energy of the particles of matter increases with the increase in temperature.

⭐ The smell of anything reaches us through the process of diffusion. And diffusion is even more faster in high temperature. So, gas from hot food diffuses faster than the cold food.

⭐ The hot temperature affects the movement of the particles in the air. So higher the temperature, the faster we smell the scent of the food. Therefore, the smell of hot food reaches us faster because that smell has higher temperature.

Answer 2

✔It is because the kinetic energy of the particles of matter increases with the increase in temperature. Therefore, the smell of hot food reaches us faster because that smell has higher temperature.
