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.
<u>Answer:</u>
<em>Indonesia Bank one of the largest consumers of electricity or energy in any form depends on fossil fuels for energy.</em>
<u>Explanation:</u>
Utilisation of solar energy for their day to day basis such that the energy need is met would mean less use of fossil fuels and lesser greenhouse gases.
And also damage to the environment and this is a very important step by Indonesia to do their bit towards environment by controlling pollution and being largest consumer turning green would mean a lot.
Ionic reaction when a metal and non metal are together a molecule is when a metal abs metal react hope this helps
we can clear specific heat:
