Answer:
<u>uniform composition.</u>
Explanation:
A phase is a part of a system with uniform composition.
- In physics and chemistry , a phase in a physically distinctive form of matter , such as solid , liquid , gas or plasma.
- A phase matter is characterised by having relatively uniform chemical and physical properities . Phases are different from states of matter.
- The states of matter (e.g ., solid , liquid , gas ) are phases but matter can exist in different phases and yet be in the same type of matter. For example , liquid mixtures can exist in multiple phases such as oily and aqueous phase.
- some different types of phases are : solid, liquid,gas , plasma etc.
- The term phase can also sometime mean describe equilibrium in phase diagram

4?
Explanation:
i think its 4, i might be wrong.
First, let's remember the concepts of spontaneous and nonspontaneous reaction:
A spontaneous reaction is a reaction that favors the formation of products at the conditions under which the reaction is occurring. This would be called an exothermic reaction, it releases energy.
A nonspontaneous reaction is a reaction that does not favor the formation of products at the given set of conditions. In order for a reaction to be nonspontaneous, it must be endothermic, accompanied by a decrease in entropy, or both.
In this case, when the reaction takes place, the temperature of the system increases which means that heat is released and heat is a form of energy. Energy is released.
The answer based on this logic would be D.
