The process in which acid reacts with base to form salt and water is callled neutralisation. This can be written as----- Hydrochloric Acid (HCI) + Sodium Hydroxide (NaOH) = Sodium Chloride (NaCl) + Water (H2O) For eg:- When a bee stings, we rub calamine solution on it. Bee sting contains formic acid and which is neutralised by rubbing bases like calamine solution.

High windspeed is accompanied by reduced air pressure. Explain

Posted by Arpita Bhattacharjee 7 years, 4 months ago

1 answers

Yogita Ingle 7 years, 4 months ago

This happens because when you blow air over the paper,the air pressure above the paper reduces.The air pressure below the paper remains the same.As the pressure below the paper is greater than that above the paper it pushes the paper up.The faster the air moves ,the more is the drop in pressure in that region.
