Option (a) is correct,
the purpose of the condenser is to de-superheat, the entering vapor, condense the vapor to a liquid, and subcool the liquid.
<h3>What is a condenser's purpose?</h3>
A condenser uses a cooling fluid to attempt to sufficiently cool down a vapor, changing its state from a vapor to a liquid. Condensers come in a variety of designs, including direct condensing, which involves coming into direct touch with the cooling fluid and the vapor.
<h3>What kind of vapor is condensed?</h3>
The vapour that needs to condense might be highly different and can even include non-condensable vapour, such as air, which greatly affects how well the condenser works.

Answer:

Explanation:
Hello, in this case, one could consider the undergoing chemical reaction as:

Thus, since 1.0 g of strontium carbonate is placed, the equilibrium equation takes the following form, excluding the solid-stated species and considering just the carbon dioxide as it is gaseous:

Hence, since at the beginning there is no carbon dioxide, its pressure at equilibrium equals Kp:

Which was clearly defined above.
Best regards.

The correct answer is A MODEL OF MOUNTAIN FORMATION.
A model refers to a representation of an idea, a process or a system, which is used to explain a specific phenomenon that can not be experienced directly. Models are often used in science to explain many phenomenon. When we are talking about a suitable model to represent an event that happens slowly, the most obvious choice from the options given above is mountain formation. This is because, the process of mountain formation occurs very slowly over a long period of time.
