In the diagram, an activity which is happening to the temperature at Point B is that: C. The temperature is not rising because the heat is being used to break the connections between the molecules.
<h3>What is matter?</h3>
Matter can be defined as any physical object or body that has both mass and takes up space. This ultimately implies that, the mass of a physical object measures the amount of matter the object contains.
<h3>What is heat?</h3>
In Science, heat is sometimes referred to as thermal energy and it can be defined as a form of energy that is transferred from a physical object (body) to another due to a difference in temperature.
By critically observing the diagram, we can reasonably infer and logically deduce that matter has dynamic states depending on the composition of its atoms and at point B the temperature remained constant (not rising) because the quantity of heat generated is used for breaking any form of connection between the molecules.

200.0 mL =0.2000 L
Molarity = number of mole solute / volume solution(L) = 0.50 mol/0.2000 L=
= 2.5 mol/L =2.5M
Answer : 2.5 M
False, photosynthesis only occurs in plant cells.
The amount of sugar in a liquid can be measured using a laser pointer and a prism. Basically, you utilize Snell's Law:
n_i*sin(θi) = n_r*sin(θr), where,
n_i = index of refraction of the incident medium
n_r = index of refraction of the refractive medium
θi = <span>angle of incidence
</span>θr = <span>angle of refraction
</span>
You make use of the laser pointer, prism, and sugar solutions in various known concentrations. You then graph the sugar concentration versus the angle of refraction. You can then determine the amount of sugar in a liquid after determining the angle of refraction of that unknown sugar solution.
