1. Convert 3.75 liters to milliliters.

• A. 3.75 ml
• B. 375 ml
• C. 3750 ml
• D. 37.5 ml

Correct answer: C

Rationale: To convert liters to milliliters, you need to multiply by 1000 since there are 1000 milliliters in 1 liter. Therefore, 3.75 liters x 1000 = 3750 milliliters. This means that option C, 3750 ml, is the correct conversion. Choices A, B, and D are incorrect because they do not reflect the correct conversion from liters to milliliters.

2. Which basic SI conversion is incorrect?

• A. 1 cm = 10 mm
• B. 1 m = 100 cm
• C. 1 km = 1000 m
• D. 1 g = 100 mg

Correct answer: D

Rationale: The correct SI conversion for grams (g) to milligrams (mg) is 1 g = 1000 mg, not 100 mg. Therefore, option D is incorrect. Option A is correct as 1 cm is equal to 10 mm, option B is correct as 1 m equals 100 cm, and option C is correct as 1 km is equivalent to 1000 m. Understanding these basic SI conversions is essential for accurate measurements and calculations in various scientific fields.

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. What is 0.5 liters in ml?

• A. 500 ml
• B. 50 ml
• C. 5 ml
• D. 0.5 ml

Correct answer: A

Rationale: To convert liters to milliliters, you need to multiply by 1000 since 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters equals 500 milliliters. This conversion is commonly used in various fields such as cooking, medicine, and science. Choice B, 50 ml, is incorrect as it represents 0.05 liters, not 0.5 liters. Choice C, 5 ml, is even smaller and represents 0.005 liters. Choice D, 0.5 ml, is incorrect as it is a tenth of the correct conversion.

5. How many feet are in one mile?

• A. 5000 feet
• B. 5280 feet
• C. 5300 feet
• D. 5500 feet

Correct answer: B

Rationale: The correct answer is B: 5280 feet. One mile is equivalent to 5280 feet. This is a standard conversion that is widely known. Choice A (5000 feet) is incorrect as it is not the exact conversion of a mile. Choice C (5300 feet) and choice D (5500 feet) are also incorrect as they do not represent the accurate conversion from miles to feet.
