What happens to the entropy of a sample of matter when it changes state from a solid to a liquid?

Answer:

  • <em>When a sample of matter changes state from a solid to a liquid, its entropy</em> <u>increases</u>.

Explanation:

The <em>entropy</em> is a thermodinamic variable that measures the disorder of radomness of a substance or system.

In the <em>solid </em>stated the particles (molecules, atoms or ions) are tightly packed, forming an organized structure. So, the particles barely can move, just vibrating around their fixed positions.

In the <em>liquid </em>state the particles are more free to move (that is why liquids flow and take the shape of the vessel in which they are contained).

Then, you can predict that <em>when a matter changes state from a solid to a liquid</em>, the parciles will gain motion leading to a higher disorder, which means that the entropy increases.

9. According to an "alternative theory", H2O is
Jlenok [28]

Answer:(4) ----accepts  a proton

Explanation:

H2O water can produce both hydrogen and   hydroxide ions

H2O --> H+ + OH-

According to the Bronsted-Lowry theory, it can be a proton donor and a proton acceptor.this means that It can donate a hydrogen ion to become its conjugate base, or  can accept a hydrogen ion to form its conjugate acid,

When , a water molecule, H2O accepts a proton it will act as a Brønsted-Lowry base especially when dissolved in a strong acidic medium. for eg

HCl + H2O(l) → H3O+(aq) + Cl−(aq)

Here, Hydrochloric acid is a strong acid and ionizes completely in  water, since it is more acidic than water, the water will act as a base.
