A physical property does not change the substance.
Solubility would be the answer since all of the rest are changing the substance. They all deal with bonds except solubility.
Answer: D. Solubility
Answer:
pour in hot water and It will disolve
Answer: Option (a) is the correct answer.
Explanation:
A weak acid is defined as an acid that dissociates partially when dissolve in water or a polar solvent.
For example, acetic acid is a weak acid and when dissolved in water it dissociates partly into ions as follows.

And, a strong acid is defined as an acid which when dissolved in water dissociates completely into ions.
For example, HCl is a strong acid and when dissolved in water it dissociates completely.

Thus, we can conclude that the statement a weak acid solution consists of mostly non-ionized acid molecules, is true.
Plasma's are gases of electrically charged particles, with equal amounts of both positive and negative charge. Only certain types of particles, called bosons, can form Bose-Einstein condensates. The other type of particle- Fermions- can only have at most one particle in each state.
