assertion

b. Both assertion and reason are true and reason is not the correct explanation of

assertion

c. Assertion is true but reason is false

d. Assertion is false, but Reason is true.​

Answer 1

$\Large{\underline{\underline{\red{\tt{\purple{\leadsto } AssertioN:-}}}}}$

Solid carbon dioxide is called dry ice.

$\Large{\underline{\underline{\red{\tt{\purple{\leadsto } ReasoN:-}}}}}$

It sublimes with the formation of intermediate product.

$\Large{\underline{\underline{\red{\tt{\purple{\leadsto } SolutioN:-}}}}}$

The Assertion is true since solid carbon dioxide is only called dry ice.

in the reason it is given that it sublimes with the formation of immediate product which is also true since dry ice undergoes the process of sublimation.

But Reason is not explaining why solid carbon dioxide is called dry ice.

Hence both assertion and reason are true but reason is not the correct explanation of Assertion. [ b ]

❒ Sublimation is the process by which a solid directly changes to gas without undergoing a change in liquid state and vice versa. substances like camphor ammonium chloride undergo sublimation.

❒ High pressure is applied to carbon dioxide to turn it into solid state. It is used for preserving things.
