1. 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.

2. When a car is driven for a long time, the pressure of air in the tires increases. This is best explained by which of the following gas laws?

• A. Boyle's law
• B. Charles' law
• C. Gay-Lussac's law
• D. Dalton's law

Correct answer: C

Rationale: Gay-Lussac's law, also known as the law of pressure-temperature, states that the pressure of a gas is directly proportional to its absolute temperature when the volume is constant. As a car is driven for a long time, the tires heat up due to friction and increased air pressure inside the tires. This results in an increase in temperature, causing the pressure of the air inside the tires to increase according to Gay-Lussac's law. Choices A, B, and D are incorrect. Boyle's law relates pressure and volume, Charles' law relates volume and temperature, and Dalton's law deals with the partial pressures of gases in a mixture.

3. Something that is viscous is thick and sticky. Another word for this might be ___________.

• A. fluid
• B. molten
• C. gelatinous
• D. malleable

Correct answer: C

Rationale: The correct word that can be used to describe something that is thick and sticky, like viscosity, is 'gelatinous.' Gelatinous refers to a substance that has a jelly-like consistency, which aligns with the characteristics of something viscous. Options A, B, and D do not accurately capture the concept of being thick and sticky. 'Fluid' implies a substance that flows easily, 'molten' refers to something melted by heat, and 'malleable' describes the ability to be shaped without breaking.

4. If a treatment mitigates symptoms, the symptoms become ______.

• A. Worse
• B. Less severe
• C. Unchanged
• D. Unbearable

Correct answer: B

Rationale: The correct answer is B: 'Less severe.' When a treatment mitigates symptoms, it means that it reduces the severity or impact of those symptoms. Therefore, the symptoms would become less severe after the treatment. Choices A, C, and D are incorrect because mitigating symptoms does not make them worse, unchanged, or unbearable; instead, it helps alleviate or reduce their intensity.

5. Convert the fraction to the simplest possible ratio: 4/6

• A. 2:3
• B. 4:7
• C. 4:6
• D. 3:5

Correct answer: A

Rationale: To simplify the fraction 4/6, you can divide both the numerator and denominator by their greatest common divisor, which is 2. Dividing 4 by 2 gives 2, and dividing 6 by 2 gives 3. Therefore, the simplest ratio of 4/6 is 2:3. Choice B (4:7) is incorrect because it does not result from simplifying the fraction. Choice C (4:6) is incorrect as it represents the original fraction, not the simplest form. Choice D (3:5) is incorrect as it does not match the simplified ratio of 4/6.
