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

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

Correct answer: A

Rationale: The correct formula to convert Celsius to Fahrenheit is (C × 9/5) + 32. This formula involves multiplying the Celsius temperature by 9/5 and then adding 32 to get the Fahrenheit temperature. Choice B is incorrect as it suggests dividing by 5/9 instead of multiplying by 9/5. Choices C and D are both incorrect because they involve using the Fahrenheit temperature in the calculation, which is not the correct method for converting Celsius to Fahrenheit.

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

• A. millimeter
• B. megabyte
• C. millipede
• D. metered

Correct answer: A

Rationale: The correct answer is 'millimeter' (A). 'mm' stands for millimeter, which is equal to one-thousandth of a meter. Choice B, 'megabyte,' is a unit of digital information storage, not a metric system unit. Choice C, 'millipede,' is an arthropod and not a metric unit. Choice D, 'metered,' is not a standard metric unit abbreviation.

3. What does the prefix 'Tera' refer to?

• A. 10^12
• B. 10^9
• C. 10^15
• D. 10^6

Correct answer: A

Rationale: The prefix 'Tera' corresponds to a factor of 10^12, which is equivalent to one trillion. It is commonly used in various fields like data storage to denote large quantities. Choice B, '10^9,' is incorrect as it corresponds to the prefix 'Giga.' Choice C, '10^15,' is incorrect as it corresponds to the prefix 'Peta.' Choice D, '10^6,' is incorrect as it corresponds to the prefix 'Mega.' Therefore, the correct answer is A.

4. Convert 0.1 liter to milliliters.

• A. 10 ml
• B. 100 ml
• C. 1000 ml
• D. 1 ml

Correct answer: B

Rationale: To convert 0.1 liters to milliliters, you need to multiply by 1000, not 10000. Therefore, 0.1 liter converts to 100 ml. Choice A (10 ml) is incorrect because it is the equivalent of 0.01 liter. Choice C (1000 ml) is incorrect as it represents 1 liter. Choice D (1 ml) is significantly less than the correct conversion.

5. What is 0.5 liters in ml?

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

Correct answer: A

Rationale: The correct answer is A: 500 ml. To convert liters to milliliters, you multiply the number of liters by 1000 because 1 liter is equal to 1000 milliliters. Therefore, 0.5 liters x 1000 = 500 milliliters. Choices B, C, and D are incorrect because they do not correctly convert 0.5 liters to milliliters based on the conversion factor of 1000 ml per liter.
