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. What is the correct formula to convert Fahrenheit to Celsius?

• A. F = (C × 9/5) + 32
• B. C = (F - 32) × 5/9
• C. C = (F - 32) × 9/5
• D. F = (C + 32) × 5/9

Correct answer: B

Rationale: The correct formula to convert Fahrenheit to Celsius is C = (F - 32) × 5/9. This formula is derived from the relationship between the two temperature scales. The incorrect choices can be ruled out as follows: A. F = (C × 9/5) + 32 - This formula is used to convert Celsius to Fahrenheit. C. C = (F - 32) × 9/5 - This formula incorrectly multiplies by 9/5 instead of dividing. D. F = (C + 32) × 5/9 - This formula does not subtract the constant 32 from the Fahrenheit value.

3. What is the value of one femtometer (fm) in meters?

• A. 10^-15 meters
• B. 10^-9 meters
• C. 10^-12 meters
• D. 10^-18 meters

Correct answer: A

Rationale: A femtometer is equivalent to 10^-15 meters. The prefix 'femto-' signifies a factor of one quadrillionth (10^-15), making choice A the correct answer. Choice B (10^-9 meters) represents a nanometer, not a femtometer. Choice C (10^-12 meters) corresponds to a picometer, not a femtometer. Choice D (10^-18 meters) is even smaller than a femtometer and refers to an attometer, not a femtometer.

4. Convert 3,540 liters to milliliters (mL).

• A. 354,000 mL
• B. 3,540,000 mL
• C. 35,400 mL
• D. 35,400,000 mL

Correct answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1,000 because there are 1,000 milliliters in 1 liter. Therefore, 3,540 liters × 1,000 = 3,540,000 milliliters. Choices A, C, and D are incorrect because they do not correctly convert liters to milliliters. A, C, and D are off by a factor of 1,000, as they do not account for the conversion factor between liters and milliliters.

5. What is the equivalent of 3,450 milliliters in liters (L)?

• A. 0.345 liters
• B. 3.45 liters
• C. 34.5 liters
• D. 345 liters

Correct answer: B

Rationale: To convert milliliters to liters, you need to divide by 1,000 since there are 1,000 milliliters in a liter. Therefore, 3,450 mL ÷ 1,000 = 3.45 liters. Choice A (0.345 liters) is incorrect as it incorrectly moves the decimal point. Choice C (34.5 liters) is incorrect as it overestimates the conversion. Choice D (345 liters) is incorrect as it overestimates by an order of magnitude.
