Which low energy state of condensed matter is characterized by structural rigitly and resistance to changes of shape or volume

Solid is the matter which has resistance to change their shape accordingly.

Explanation:

Solid, because when matter is in solid-state, particles are more rigid and motionless with the negligible rotational effect but face vibrations hence not resistant enough to change shape and volume. The molecules and atoms in solid are packed in a fixed position with respect to one another. This is the ‘low energy’ state of condensed matter which has confined shape.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
