D. Even though the temperature is the same, container B has more thermal energy, since it has more liquid than container A.
<u>Explanation:
</u>
Whenever there is an increase in the volume of the pink liquid, it is due to the increase in temperature.
When the temperature increases, the molecules move farther apart as much as possible.
When the molecules moves apart from each other and collide with each other, so that its kinetic energy also increases, So thermal energy of the container B is more compared to the container A.
Answer:
a semi-crystalline structure is formed, which holds the water molecules apart, making ice less dense than liquid water, such that it floats. This means that it insulates the water beneath, allowing organisms in the liquid water to survive. Cohesion is the tendency of molecules within a substance to ‘ stick together
explanation:
Answer is: Prepare to measure pH change.
For example for strong acid-base titration, sodium hydoxide and hydrochloric can be used.
Balanced chemical reaction: HCl + NaOH → NaCl + H₂O.
In this reaction pH of equivalence point will be always 7.
Equivalence point is the point which there is stoichiometrically equivalent amounts of acid and base.
Chemist can draw pH curve (graph showing the change in pH of a solution, which is being titrated) for titration and determine equivalence point.
Near equivalence point indicator should change color, so we must pick indicator who change color near pH of equivalence point.
