Question

BE THE FIRST TO BE BRAINLIEST. If we add potassium permanganate crystals in cold water tank of 1000l after the some time the whole solution will get the colour so in this case the particles travel more distance that is from bottom to
upwards.


But in the case of cold food the particles of cold gases produced by the food can travel only shorter distances that's why we cannot sense the smell of cold food from considerable or long distances
But in the first case the particles can travel more distance but in the second case it cannot travel why???
I am really confused

Answer 1

in first case it is in water and water have less space than air it is enough to fix the particles of crystal another reason is - more kinetik energy ...it change to pink
in second case it have less kine tik energy
