ATI TEAS 7
TEAS Reading Practice Test
1. What is the significance of the term 'Bunburying' in the context of the play?
- A. It highlights the characters' desire to lead a double life and escape social obligations.
- B. It reflects the characters' indifference to social conventions.
- C. It demonstrates the characters' willingness to deceive themselves and others.
- D. It serves as a metaphor for the characters' struggle to conform to societal expectations.
Correct answer: A
Rationale: 'Bunburying' is significant in the play because it emphasizes the characters' desire to lead double lives and avoid the strict societal expectations placed upon them. The term highlights their need to escape the confines of social obligations through deception and subterfuge. By maintaining a fictional persona like Bunbury, the characters can freely navigate between different social spheres, allowing them to explore personal freedom and evade the constraints of their social status. This escapade showcases their yearning for independence and autonomy, contrasting with the societal norms they are expected to conform to. Choices B, C, and D are incorrect because 'Bunburying' in the context of the play is more about evading social duties through a dual identity, rather than reflecting indifference, willingness to deceive, or struggling to meet societal expectations.
2. Which of the following statements describes a chemical property of water?
- A. Water has a pH of 1.
- B. A water molecule contains 2 hydrogen atoms and 1 oxygen atom.
- C. A water molecule contains 2 oxygen atoms and 1 hydrogen atom.
- D. The chemical formula for water is HO.
Correct answer: B
Rationale: The correct answer is B because a water molecule consists of two hydrogen atoms and one oxygen atom, which is a fundamental chemical property of water. The pH of water is not a property of the water molecule itself but rather a measure of its acidity or alkalinity. Choice C is incorrect as it describes a different molecule, not water. Choice D provides an incorrect chemical formula for water, which is H2O.
3. Which of the following units is used to express concentration as a mass of solute per unit volume of solution?
- A. Molality (m)
- B. Molarity (M)
- C. Weight percent (%)
- D. Parts per million (ppm)
Correct answer: A
Rationale: Molality (m) is the unit used to express concentration as a mass of solute per unit volume of solution. It is calculated by dividing the mass of solute in grams by the mass of the solvent in kilograms. Molality is preferred over molarity when there are large temperature variations as it is temperature-independent, making it a more accurate measure of concentration. Molarity (B) is the unit used to express concentration as moles of solute per liter of solution, weight percent (C) is the mass of solute per 100 parts of the total mass of the solution, and parts per million (D) is used to express very small concentrations where 1 ppm is equivalent to 1 mg of solute per liter of solution.
4. What is the volume of a ball with a diameter of 7 inches?
- A. 165.7 in³
- B. 179.6 in³
- C. 184.5 in³
- D. 192.3 in³
Correct answer: A
Rationale: To find the volume of a sphere, the formula V = (4/3)πr³ is used, where r is the radius of the sphere. Given that the diameter of the ball is 7 inches, the radius (r) would be half of the diameter, which is 3.5 inches. Plugging this value into the formula: V = (4/3)π(3.5)³ = (4/3)π(42.875) ≈ 165.7 in³. Therefore, the correct answer is A. Choice B, C, and D are incorrect as they do not accurately represent the volume of the ball with a diameter of 7 inches.
5. Which of the following is the positively charged subatomic particle found in the nucleus of an atom?
- A. Electron
- B. Proton
- C. Neutron
- D. Quark
Correct answer: B
Rationale: The correct answer is B: Proton. Protons are positively charged subatomic particles found in the nucleus of an atom. They have a mass of approximately 1 atomic mass unit (amu) and a charge of +1. The number of protons in an atom's nucleus determines the atomic number of the element, which is a unique identifier for each element. Choice A, Electron, is incorrect as electrons are negatively charged particles found outside the nucleus. Choice C, Neutron, is incorrect as neutrons are neutral particles found in the nucleus. Choice D, Quark, is incorrect as quarks are elementary particles that combine to form protons and neutrons, but they are not the positively charged particle found in the nucleus of an atom.
