1. What is the conversion factor from milliliters to liters?

• A. 0.001 liters
• B. 0.01 liters
• C. 1 liter
• D. 10 liters

Correct answer: A

Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in a liter. Therefore, the correct conversion factor is 0.001 liters (1 liter = 1000 milliliters). Choice B (0.01 liters) is incorrect as it suggests dividing by 100, which is not the correct conversion. Choice C (1 liter) is incorrect because it is the equivalent value in liters, not the conversion factor. Choice D (10 liters) is incorrect as it is not the correct conversion of milliliters to liters.

2. What does 'kg' stand for in the metric system?

• A. kilogram
• B. keg
• C. kroner
• D. kraken

Correct answer: A

Rationale: 'kg' stands for kilogram, the unit of mass equal to 1,000 grams. In the metric system, 'kg' specifically represents the unit of mass, making 'kilogram' the correct choice. The other choices, 'keg,' 'kroner,' and 'kraken,' do not represent the standard unit of mass in the metric system and are therefore incorrect.

3. How many millimeters are in 5 centimeters?

• A. 50 mm
• B. 500 mm
• C. 5 mm
• D. 500 cm

Correct answer: B

Rationale: To convert centimeters to millimeters, you multiply by 10 since there are 10 millimeters in a centimeter. Therefore, 5 centimeters x 10 = 50 millimeters, making choice A the correct answer. Choice C, '5 mm,' is incorrect as it represents the original quantity in millimeters. Choice D, '500 cm,' is incorrect as it converts the centimeters to centimeters instead of millimeters.

4. What is the expression 1 in. = 2.54 cm properly called?

• A. Law of Conservation of Units
• B. International Yard
• C. Standard Conversion Factor
• D. Exact Equivalent

Correct answer: D

Rationale: The correct answer is D: Exact Equivalent. The expression 1 inch = 2.54 cm is a direct and precise conversion between inches and centimeters, making it an exact equivalent. It is not related to the Law of Conservation of Units (A) as this principle pertains to the conservation of physical quantities in a system. The International Yard (B) is a unit of measurement, but it is not the term for the given expression. Similarly, while the conversion factor in the expression is standard, it is specifically an exact equivalent and not just a general standard conversion factor (C). Therefore, D is the most appropriate term to describe this specific conversion relationship.

5. What is the term for the amount of space an object occupies?

• A. mass
• B. volume
• C. density
• D. area

Correct answer: B

Rationale: The correct term for the amount of space an object occupies is 'volume.' Volume refers to the three-dimensional space that an object occupies and is measured in cubic units like cubic meters. 'Mass' (Choice A) refers to the amount of matter in an object, 'density' (Choice C) is the mass per unit volume of a substance, and 'area' (Choice D) is the measurement of the extent of a surface.
