1. The specific heat capacity of tin is 217 J/(g°C). Which of these materials would require about twice as much heat as tin to increase the temperature of a sample by 1°C?

• A. Copper [0.3844 J/(g°C)]
• B. Iron [0.449 J/(g°C)]
• C. Gold [0.1291 J/(g°C)]
• D. Aluminum [0.904 J/(g°C)]

Correct answer: D

Rationale: The correct answer is D: Aluminum. The specific heat capacity of aluminum is 0.904 J/(g°C), which is approximately 4 times that of tin. For a material to require about twice as much heat as tin to increase the temperature by 1°C, it should have a specific heat capacity roughly double that of tin. Therefore, aluminum fits this criterion better than the other options. Gold has a much lower specific heat capacity than tin, so it would require less, not more, heat to increase the temperature by 1°C. Copper and Iron also have specific heat capacities lower than tin, making them incorrect choices for requiring twice as much heat as tin.

2. What word is best to fill in the blank in the following sentence? Jenny loaned Luis 50 dollars, and he repaid ___________ within the month.

• A. her
• B. she
• C. him
• D. its

Correct answer: C

Rationale: In this sentence, the pronoun should refer to Luis, who borrowed the money. Since Luis is a male, the correct pronoun to use in this context is 'him.' Therefore, the correct answer is 'him.' Choices A, B, and D are incorrect as they do not match the gender of Luis or do not make sense in the context of the sentence.

3. What is the meaning of Collusion?

• A. Cooperation
• B. Conspiracy
• C. Separation
• D. Rejection

Correct answer: B

Rationale: The correct answer is B: 'Conspiracy.' Collusion refers to a secret agreement or conspiracy, often for deceitful or illegal purposes. Choice A, 'Cooperation,' is incorrect as collusion implies a deceptive or dishonest agreement, not a genuine cooperation. Choice C, 'Separation,' is incorrect as it denotes the opposite of collusion, which involves working together secretly. Choice D, 'Rejection,' is unrelated to collusion, which involves secret cooperation for deceptive purposes.

4. What is the name of the process by which a gas turns into a liquid?

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

Correct answer: B

Rationale: The correct answer is B: Condensation. Condensation is the process where gas transforms into a liquid. When gas cools down, it loses energy and its particles come closer, leading to the formation of liquid droplets. Sublimation is the direct transition from solid to gas without passing through the liquid state. Evaporation is the process of liquid turning into a gas, and deposition is the transition of gas directly into a solid. Therefore, choices A, C, and D are incorrect as they describe different phase transitions.

5. When an individual is under stress, hormones are released. Which of the following is not one of the locations in which hormones are released when under stress?

• A. Posterior pituitary
• B. Hypothalamus
• C. Adrenal cortex
• D. Parathyroid

Correct answer: D

Rationale: During stress, hormones are released from the adrenal cortex, posterior pituitary, and hypothalamus to help the body respond. The parathyroid gland, however, is not typically involved in the stress response by releasing hormones. The posterior pituitary releases hormones like oxytocin and vasopressin, the hypothalamus secretes corticotropin-releasing hormone (CRH) and vasopressin, while the adrenal cortex releases cortisol and aldosterone in response to stress. Therefore, the correct answer is 'Parathyroid.'
