He said that there was strength in unity. Each dove picked up a portion of the net and together they flew off carrying the net with them.

Answer 2

Explanation:

CO2has neither fixed volume nor a fixed shape and is hence a gas. It exerts pressure due to collision of the molecules. CO2may be liquefied by reducing temperature or by increasing pressure. Solid CO2gets converted directly into gaseous state without coming into liquid state and is hence called dry ice.
