Answer:
D. Pressure and temperature.
Explanation:
The answer is D because when water molecules (H2o) have heat and pressure added it will boil. For exampe if your cooking pasta, you add water to your pan and when you add heat and put the lid of the pan it will boil.
The phenomenon that best explains the miscibility of heptane in pentane is that both are non-polar compounds.
<h3>Solubility of compounds</h3>
Solubility is defined as the ability of a solute or substance to dissolve in a given solvent and at a particular temperature.
Heptane is a straight-chain alkane hydrocarbon that contains 7 carbon atoms. It is a non polar solvent.
Pentane is also a straight-chain alkane hydrocarbon that contains 5 carbon atoms. It is also a non- polar solvent.
Both pentane and heptane are non-polar because the atoms in their molecules share electrons equally. They are able to dissolve each other because they are alike.

In science, a model is a representation of an idea, an object or even a process or a system that is used to describe and explain phenomena that cannot be experienced directly. Models are central to what scientists do, both in their research as well as when communicating their explanations.
Models have a variety of uses – from providing a way of explaining complex data to presenting as a hypothesis. There may be more than one model proposed by scientists to explain or predict what might happen in particular circumstances. Often scientists will argue about the ‘rightness’ of their model, and in the process, the model will evolve or be rejected. Consequently, models are central to the process of knowledge-building in science and demonstrate how science knowledge is tentative.
Answer: it’s b)
Explanation: that’s the only difference that is listed
Answer:
<h2>10 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>10 m/s²</h3>
