$CO_{2}$ is a gas. Write any two of its gaseous properties to justify this. How can we liquefy this gas? Solid $CO_{2}$ is also known as dry ice. Why?

(N/A) $CO_{2}$ has neither a fixed volume nor a fixed shape,which is a characteristic property of gases.
It exerts pressure on the walls of its container due to the random collisions of its molecules.
$CO_{2}$ can be liquefied by applying high pressure and lowering the temperature.
Solid $CO_{2}$ is known as dry ice because it undergoes sublimation,meaning it converts directly from a solid state to a gaseous state at atmospheric pressure without passing through the liquid phase.
