1. 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.

2. Convert 35.40 kilograms to grams (g).

• A. 354 g
• B. 35,400 g
• C. 3,540 g
• D. 3.54 g

Correct answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1,000 since there are 1,000 grams in a kilogram. Therefore, 35.40 kg × 1,000 = 35,400 grams. Choice A (354 g) is incorrect because it is off by a factor of 10. Choice C (3,540 g) is incorrect as it is off by a factor of 100. Choice D (3.54 g) is incorrect as it represents kilograms instead of grams.

3. What is 0.1 kg in grams?

• A. 100 g
• B. 10 g
• C. 1 g
• D. 0.1 g

Correct answer: A

Rationale: To convert kilograms to grams, you need to multiply by 1,000 since there are 1,000 grams in a kilogram. Therefore, 0.1 kg equals 100 grams. Choice B (10 g) is incorrect because it represents converting 0.01 kg to grams. Choice C (1 g) is incorrect as it reflects the conversion of 0.001 kg to grams. Choice D (0.1 g) is the value in grams equivalent to 0.01 kg, not 0.1 kg.

4. What is the base unit for liquid volume in the metric system?

• A. Milliliters
• B. Liters
• C. Gallons
• D. Liters

Correct answer: B

Rationale: The correct answer is B: Liters. In the metric system, liters are the base unit for liquid volume. Milliliters, though a metric unit, are a smaller unit of volume and not the base unit. Gallons, on the other hand, are part of the imperial system and not a metric unit for volume. Option D is a duplicate of option B, making it incorrect.

5. What is 0.04 grams converted to milligrams?

• A. 40 mg
• B. 4 mg
• C. 400 mg
• D. 0.4 mg

Correct answer: A

Rationale: To convert grams to milligrams, you need to multiply by 1000, not 10000. Therefore, to convert 0.04 grams to milligrams, you multiply 0.04 by 1000, which equals 40 mg. Choice A (40 mg) is the correct answer. Choice B (4 mg) is incorrect as it represents converting 0.004 grams to milligrams. Choice C (400 mg) is incorrect as it is 10 times the correct conversion. Choice D (0.4 mg) is incorrect as it is 10 times smaller than the correct conversion.
