Question

Why air moves from high pressure to low

Answer 1

I think this is because

in high pressure every molecules are tightly packed but in case of low pressure molecules are weakly packed so these molecules moves very easily then high pressure molecules and as you know that in chemistry ever particles want freedom for their stability so that why air moves high pressure to low pressure to attain that stability

Answer 2

Listen dear, try to understand :-

An area is said to have low pressure if the amount of air in that region is very low. (scarcity of air)
And the region that has high pressure means that there is excess of presence of air.( having extra air)
So, the extra amount of air rushes from high pressure area rushes towards the region of low pressure to make a balance.
