The bonds in a substance breaks down in a phase change from liquid to gas and the molecules move independently of each other.
It is conventional to describe chemical bonds with the aid of elastic materials such as a rubber band. This analogy can only apply to covalent bonds between atoms in which the bonds between atoms are stretched.
However, in discussing the bonds in a substance when considering phase changes, this analogy breaks down because for a phase change from liquid to gas, the bonds break completely and particles can move independently of each other.

<span>According to Le Chatelier's Principle, the position of
equilibrium moves to counteract the change, the position of equilibrium
will move so that the concentration of
products of chemical reaction increase, if:</span>
<span>1) increase temperature, because this endothermic reaction.</span>
<span>2) increase concentration of reactant.</span>
<span>3) decrease pressure of the system, so reaction moves to direction where is more molecules.</span>

Answer:
prokaryot cells doesn't have core or kernel like archeabacteria and eubacteria , but eukaryotes have it .
Explanation:
Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA
