Explanation:
Hi there,
To get started, please recall what heating curves are, latent heat, and enthalpy of phase changes (vaporization, fusion).
In a heating curve for ice water, temperature is the dependent variable (y-axis) and heat or time elapsed is independent variable (x-axis). There are three sloped portions. These sloped portions are showing where the <u>mixture is not changing phase, and is in a specific phase.</u> (solid first, then liquid then gas).
The reason is because the addition of more heat in time is causing the temperature to rise, so the mixture is getting "hotter." The temperature is still rising, yet the mixture is still in the current phase (depending on where you are referencing on the curve).
The two leveled portions are the process of melting (first leveled) and boiling (second leveled). The reason they are horizontal is because the addition of heat is not causing temperature to go up. The molecules are in the process of distributing heat in a different form by changing the mixtures entire structure (AKA phase), and so they are flat because the average kinetic energy from heat is being used change phase.

Answer:
A. The sum of all the forces acting on an object.
According to the chart concluded by Charity's observation, her rabbit prefers lettuce over celery and carrots and majority of rabbit species follows the same.
Answer: Statement A
<u>Explanation:</u>
As per the biological observations, it's is proven that leafy vegetables such as lettuce is worth for rabbits health as compared to carrots being involved in their daily diets as it contains sugar. According to the observations that Charity has gone through a month for her pet rabbit, it seems that her rabbit is most likely preferring lettuce over carrots and celery.
Talking about celery, it's not among the leafy kinds of rabbit's diet and should only worth of only 15% of space in daily diet. Although rabbits often eat celery, but most of the species primarily rely on lettuce and parsley which seems the case with Charity's pet. Hence, the statement A is likely to be the best answer according to the observations that the rabbit prefers lettuce over carrot and celery.
