1. What is the process called in which a substance changes from a gas to a liquid?

• A. Condensation.
• B. Evaporation.
• C. Sublimation.
• D. Vaporization.

Correct answer: A

Rationale: Condensation is indeed the correct answer. It is the process by which a substance changes from a gas to a liquid. This occurs when the temperature of a gas decreases enough for its particles to lose energy and come together to form a liquid. On the other hand, evaporation is the process of a liquid changing to a gas. Sublimation is the direct transition of a substance from a solid to a gas without passing through the liquid phase. Vaporization, on the other hand, is the general term for the process of a liquid changing to a gas, which includes both evaporation and boiling.

2. What happens to the density of a gas when its temperature increases at constant pressure?

• A. It increases.
• B. It decreases.
• C. It remains the same.
• D. Information is insufficient.

Correct answer: B

Rationale: When the temperature of a gas increases at constant pressure, the average kinetic energy of the gas molecules increases. This leads to the gas molecules moving faster and spreading out more, which causes them to occupy a larger volume. As a result, the density of the gas decreases because the same number of gas molecules are now distributed over a larger space. Choice A is incorrect because as the gas molecules spread out, the density decreases. Choice C is incorrect because the increase in temperature leads to a decrease in density due to the increased volume occupied by the gas molecules. Choice D is incorrect because with the provided scenario of temperature increase at constant pressure, the effect on density can be determined.

3. What is the maximum volume of air that the lungs can hold after a full forced inhalation?

• A. Inspiratory capacity
• B. Tidal volume
• C. Total lung capacity
• D. Vital capacity

Correct answer: C

Rationale: Total lung capacity is the correct term for the maximum volume of air that the lungs can hold after a full forced inhalation. It represents the sum of all lung volumes, including tidal volume, inspiratory reserve volume, and expiratory reserve volume. Inspiratory capacity refers to the maximum volume of air inspired from the end-expiratory level. Tidal volume is the volume of air inspired or expired during normal breathing. Vital capacity is the maximum volume of air that can be exhaled after a maximum inhalation, not the total volume the lungs can hold.

4. Which of the following is an example of deliberate plagiarism?

• A. A student copies an informational source intending to paraphrase it.
• B. A writer forgets to include quotation marks around a direct quote.
• C. A student submits a paper they found on the internet.
• D. A writer omits a source citation because they believe the information is common knowledge.

Correct answer: C

Rationale: The correct answer is C. Submitting a paper found on the internet as one's own work is a clear example of deliberate plagiarism. Choice A is not deliberate plagiarism as the student intends to paraphrase the source, although it may still be considered plagiarism if not properly cited. Choice B is a form of plagiarism known as improper citation but does not involve deliberate intent to pass off someone else's work as one's own. Choice D is also a form of plagiarism known as inadequate citation or failure to attribute, but it does not constitute deliberate plagiarism as the writer's intention is not to deceive but rather a failure in acknowledging sources properly.

5. Every morning we would wake up, eat breakfast, and break camp. Which of the following is the correct revision for the sentence?

• A. NO CHANGE
• B. we would wake up, eat breakfast, and break camp.
• C. would we wake up, eat breakfast, and break camp?
• D. we are waking up, eating breakfast, and breaking camp.

Correct answer: B

Rationale: The correct answer is B: 'we would wake up, eat breakfast, and break camp.' The original sentence is a list of actions in the past, so the verb 'break' should also be in the past tense to maintain consistency. Choice A is incorrect because 'broke' is incorrect in this context. Choice C is a question format and does not fit the original sentence structure. Choice D changes the tense to present progressive, which does not match the past tense context of the sentence.
