1. How many ounces are in 0.5 liters?

• A. 16.91 oz
• B. 15.91 oz
• C. 17.91 oz
• D. 18.91 oz

Correct answer: A

Rationale: To convert liters to ounces, you need to multiply the volume in liters by 33.814. In this case, 0.5 liters multiplied by 33.814 equals approximately 16.91 ounces. This conversion is commonly used in culinary and liquid measurements. Choices B, C, and D are incorrect as they do not reflect the correct conversion factor from liters to ounces.

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. Which metric prefix represents 10^-2?

• A. centi
• B. milli
• C. nano
• D. deci

Correct answer: A

Rationale: The metric prefix 'centi-' signifies 10^-2, denoting one-hundredth of a unit. For instance, 1 centimeter equals 0.01 of the base unit. Choice B, 'milli,' represents 10^-3, 'nano' in Choice C represents 10^-9, and 'deci' in Choice D stands for 10^-1. Therefore, the correct answer is 'centi.'

4. Convert 354,000 millimeters to meters (m).

• A. 354 m
• B. 354 m
• C. 354,000 km
• D. 35,400 m

Correct answer: B

Rationale: To convert millimeters to meters, you need to divide by 1,000 since there are 1,000 millimeters in a meter. Therefore, 354,000 mm ÷ 1,000 = 354 meters. Choice A, '354 m,' is correct as it represents the converted value. Choice C, '354,000 km,' is incorrect as it suggests converting to kilometers instead of meters. Choice D, '35,400 m,' is incorrect as it is not the result of the correct conversion calculation.

5. How many milliliters are in 1 liter?

• A. 10 mL
• B. 100 mL
• C. 1,000 mL
• D. 10,000 mL

Correct answer: C

Rationale: The correct answer is 1,000 milliliters in 1 liter. The conversion from liters to milliliters involves multiplying by 1,000 since 1 liter is equivalent to 1,000 milliliters. Choice A, 10 mL, is incorrect as it represents only a fraction of a liter. Choice B, 100 mL, is also incorrect as it is one-tenth of a liter. Choice D, 10,000 mL, is significantly larger than the correct answer and represents 10 liters, not 1 liter.
