उत्तर
Two gas jars A and B are taken. A is filled with air and B with dry HCI gas. B is inverted over A, kept for few minutes and then jar is removed. Now a rod dipped in ammonium hydroxide is introduced into the jar A, white fumes are seen. This shows that HCI displaces the air since it is heavier than air.
