Metric Conversions for TEAS 7

1. What mnemonic helps in recalling metric conversions?

A. King Hector Died By Drinking Chocolate Milk
B. Kittens Have Delighted By Dancing Cool Moves
C. Memorize Your Units Well
D. Convert These Every Time

Correct answer: A

Rationale: The mnemonic 'King Hector Died By Drinking Chocolate Milk' aids in recalling metric prefixes in order: kilo-, hecto-, deca-, base (meter, liter, gram), deci-, centi-, milli-. Choice B does not provide a relevant mnemonic for metric conversions. Choices C and D do not offer a helpful phrase for remembering metric prefixes, making them incorrect.

2. Which of the following sentences uses proper capitalization?

A. Last summer, my family went on a trip to Niagara Falls in New York.
B. Last summer, my family went on a trip to Niagara Falls in New York.
C. Last summer, my family went on a trip to Niagara Falls in New York.
D. Last summer, my family went on a trip to Niagara Falls in New York.

Correct answer: C

Rationale: The correct sentence uses lowercase 'summer' and capitalizes 'Niagara Falls.' Choice A incorrectly capitalizes 'Summer,' while Choice B incorrectly capitalizes 'niagara falls' and should have 'New York' capitalized. Choice D incorrectly capitalizes 'Summer' and 'new york.'

3. Edema, characterized by swelling due to fluid buildup, can be a sign of:

A. Heart failure
B. Liver disease
C. Lymphatic system dysfunction
D. All of the above

Correct answer: D

Rationale: Edema is the swelling caused by fluid retention in the body tissues. It can indicate various underlying conditions. Heart failure can lead to fluid buildup due to the heart's ineffective pumping. Liver disease can cause edema by reducing protein production, leading to fluid leakage into tissues. Dysfunction of the lymphatic system can impair fluid drainage, contributing to edema. Therefore, all of the above conditions can manifest with edema, making the correct answer 'All of the above.' Choices A, B, and C are all valid causes of edema, making them incorrect when considered individually. Selecting 'All of the above' encompasses all the possible causes of edema.

4. What is the stoichiometric coefficient of nitrogen (N2) in the balanced equation for the Haber process: N2 + 3H2 â†’ 2NH3?

A. 1
B. 2
C. 3
D. 4

Correct answer: A

Rationale: In the balanced equation for the Haber process: N2 + 3H2 â†’ 2NH3, the stoichiometric coefficient of nitrogen (N2) is 1. This means that one molecule of nitrogen reacts with three molecules of hydrogen to produce two molecules of ammonia. The coefficient '1' indicates the mole ratio of N2 in the reaction. Choice B, 2, is incorrect because it represents the coefficient for ammonia (NH3) in the balanced equation. Choice C, 3, is incorrect as it corresponds to the coefficient of hydrogen (H2). Choice D, 4, is not the correct stoichiometric coefficient for nitrogen (N2) in this equation.

5. Which type of waves travel by causing particles in the medium to vibrate parallel to the direction of wave travel?

A. Transverse waves
B. Longitudinal waves
C. Surface waves
D. Electromagnetic waves

Correct answer: B

Rationale: Longitudinal waves are waves in which particles of the medium vibrate parallel to the direction of wave travel. These waves are characterized by compressions and rarefactions in the medium, where particles move back and forth in the same direction as the wave. Transverse waves, on the other hand, cause particles to vibrate perpendicular to the direction of wave travel. Surface waves combine both longitudinal and transverse motion, making them different from pure longitudinal waves. Electromagnetic waves, unlike longitudinal and transverse waves, do not require a medium and can travel through a vacuum.
