Question

Assertion [A]: A brick has a definite shape.
Reason [R]: Solids have strong intermolecular force of attraction between their particles.

• A. Both [A] and [R] are correct
• B. Both [A] and [R] are incorrect
• C. [A] is incorrect, but [R] is correct
• D. [A] is correct, but [R] is incorrect

Answer 1

The correct option is A Both [A] and [R] are correct

Solid is a state of matter. Solids have strong intermolecular force of attraction between their particles. Due to this force, they have very little interparticle space. Hence, they resist any change in shape and volume.
A brick possesses all the above properties. Thus, it is a solid and has a definite shape.
