Explanation:
What is the purpose of the scientific method?
<em><u>ans/</u></em>
the goal of any scientific method is to solve a problem or to better understand an observed event.
b.
i. What does the law of conservation of energy say?
<em><u>ans/</u></em>
The law of conservation of energy states that energy can neither be created nor destroyed - only converted from one form of energy to another.
ii. List two different kinds of energy.
<em><u>ans/</u></em>
Potential energy.
Kinetic energy.
iii. What does the law say about changes energy can undergo?
<em><u>ans/</u></em>
The implication of the Law of Conservation of Energy is that for any energy conversion, if a certain type, or form, of energy gets reduced by a certain amount, then another type of energy must increase by the same amount.
Answer:
A) H₂O at 120°C
Explanation:
It is possible to think the higher temperature, the greatest degree of disorder. That is because with a high temperature, vibrations of molecules increases.
In general, at low temperatures, the molecules are in solid state (The lowest degree of disorder), increasing its temperature, molecules becomes in liquids, and, with more temperature, are gases (The greatest degree of disorder).
Thus, the sample that has the greatest degree of disorder is:
<h3>A) H₂O at 120°C</h3>
