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.
Answer:
6.2 moles of K2CO3 can be converted to 856.8741 grams.
Jets streams play a key role in determining the weather because they usually separate colder air and warmer air.
