TEAS 7 science quizlet
1. What is the term for the process of a liquid changing into a gas?
- A. Evaporation
- B. Boiling
- C. Condensation
- D. Sublimation
Correct answer: A
Rationale: The correct answer is 'Evaporation.' Evaporation is the process by which a liquid changes into a gas at any temperature, while boiling specifically refers to the rapid vaporization of a liquid only at its boiling point. Condensation is the opposite process of gas turning into a liquid, and sublimation is the direct transition from solid to gas without passing through the liquid phase.
2. Which of the following factors would increase the solubility of a gas in a liquid?
- A. Decreasing temperature
- B. Increasing pressure
- C. Decreasing surface area
- D. Increasing particle size
Correct answer: B
Rationale: The correct answer is increasing pressure. According to Henry's Law, the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid. Therefore, increasing pressure would force more gas molecules into the liquid, leading to an increase in solubility. Conversely, decreasing temperature, decreasing surface area, and increasing particle size would not directly impact the solubility of a gas in a liquid. Decreasing temperature typically decreases solubility as gases are less soluble at lower temperatures. Decreasing surface area and increasing particle size are related to surface area and not the pressure above the liquid, thus not affecting solubility as pressure does.
3. Which of the following is an example of revision?
- A. Typing the first draft of an essay
- B. Reading sentences for clarity and making necessary changes
- C. Creating a list of all sources used within the essay
- D. Mapping out possible topics and subtopics
Correct answer: B
Rationale: The correct answer is B because revision involves reviewing and editing sentences for clarity and making necessary changes to improve the overall quality of the writing. Choice A is incorrect because typing the first draft is part of the drafting process, not revision. Choice C is incorrect as creating a list of sources is related to research and citation but not revision. Choice D is incorrect as mapping out topics and subtopics is typically done during the outlining or prewriting stages, not during the revision process.
4. What is a reaction between an acid and a base known as?
- A. Precipitation
- B. Neutralization
- C. Oxidation-reduction
- D. Photolysis
Correct answer: B
Rationale: The correct answer is B: Neutralization. When an acid and a base react, they neutralize each other's properties, resulting in the formation of water and a salt. Choice A, 'Precipitation,' refers to the formation of a solid from a solution during a chemical reaction. Choice C, 'Oxidation-reduction,' involves the transfer of electrons between reactants. Choice D, 'Photolysis,' is a reaction where a compound is broken down into smaller components by light energy. Therefore, the most appropriate term for a reaction between an acid and a base is neutralization.
5. Identify the appositive in the following sentence: 'My favorite author, Agatha Christie, wrote many detective novels.'
- A. favorite
- B. Agatha Christie
- C. many
- D. novels
Correct answer: B
Rationale: In the sentence, 'Agatha Christie' is the appositive. An appositive is a noun or noun phrase that renames or clarifies another noun or pronoun in a sentence. In this case, 'Agatha Christie' renames the noun 'author.' The appositive provides additional information about the noun it follows, enhancing the reader's understanding. Choices A, C, and D are not appositives. 'Favorite' is an adjective describing 'author,' 'many' is an adjective describing 'novels,' and 'novels' is the direct object of the verb 'wrote,' not an appositive.
