TEAS version 7 quizlet science
1. Which property of a substance describes how much matter is packed into a given space?
- A. Mass
- B. Volume
- C. Weight
- D. Density
Correct answer: D
Rationale: Density is the property of a substance that describes how much matter is packed into a given space. It is calculated by dividing the mass of the substance by its volume. Mass refers to the amount of matter in an object, volume is the amount of space an object occupies, and weight is the force of gravity acting on an object's mass. Density specifically relates to how tightly packed the particles of a substance are. In this context, density is the most appropriate answer as it directly addresses how matter is packed into a given space. Mass and weight are related to the quantity of matter and the force of gravity, respectively, but do not directly describe the compactness of matter in a given space. Volume, on the other hand, refers to the space occupied by an object, not the amount of matter packed into that space.
2. What is the main idea of the paragraph?
- A. Coal mining is a dangerous job.
- B. Coal mining is a dirty job.
- C. Coal mining takes place underground.
- D. Coal miners risk injury on a daily basis.
Correct answer: A
Rationale: The main idea of the paragraph is to highlight the dangers associated with coal mining. The sentence 'Coal miners risk injury and health issues on a daily basis' supports the concept that coal mining is a dangerous job. Choice B is incorrect as it focuses on cleanliness rather than safety. Choice C is incorrect as the location of coal mining is not the primary focus of the paragraph. Choice D is incorrect as it does not encompass the full extent of risks mentioned in the paragraph.
3. What is the relationship between work, force, and displacement?
- A. Work is directly proportional to force but inversely proportional to displacement
- B. Work is directly proportional to both force and displacement
- C. Work is inversely proportional to force but directly proportional to displacement
- D. Work is inversely proportional to both force and displacement
Correct answer: B
Rationale: Work is directly proportional to both force and displacement. The work done on an object is calculated by multiplying the force applied to the object by the distance the object moves in the direction of the force. Therefore, work is directly proportional to both force and displacement. Choice A is incorrect because work is not inversely proportional to displacement. Choice C is incorrect because work is not inversely proportional to force. Choice D is incorrect because work is not inversely proportional to both force and displacement.
4. Convert 35.40 kilograms to grams (g).
- A. 354 g
- B. 35,400 g
- C. 3,540 g
- D. 3.54 g
Correct answer: B
Rationale: To convert kilograms to grams, you need to multiply by 1,000 since there are 1,000 grams in a kilogram. Therefore, 35.40 kg × 1,000 = 35,400 grams. Choice A (354 g) is incorrect because it is off by a factor of 10. Choice C (3,540 g) is incorrect as it is off by a factor of 100. Choice D (3.54 g) is incorrect as it represents kilograms instead of grams.
5. What is a contraceptive method that uses hormones to prevent ovulation?
- A. Spermicide
- B. Barrier method (condom, diaphragm)
- C. Combined oral contraceptive pill
- D. Intrauterine device (IUD)
Correct answer: C
Rationale: The correct answer is the Combined oral contraceptive pill (C). This method contains hormones (estrogen and progestin) that prevent ovulation, making it an effective contraceptive. Spermicide (A) is a substance that kills sperm and does not use hormones to prevent ovulation. Barrier methods (B) like condoms and diaphragms physically block sperm but do not involve hormone-induced prevention of ovulation. Intrauterine devices (IUDs) (D) prevent pregnancy through different mechanisms, such as altering the uterine environment and preventing sperm from fertilizing the egg, not by hormone-induced prevention of ovulation.
