1. Convert 0.5 liters to milliliters.

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

Correct answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000 as there are 1000 milliliters in 1 liter. Therefore, when converting 0.5 liters to milliliters, the correct answer is 0.5 x 1000 = 500 ml. Choice A (50 ml) is incorrect because it represents the conversion of 0.05 liters, not 0.5 liters. Choice C (5 ml) is incorrect as it represents the conversion of 0.005 liters. Choice D (0.5 ml) is incorrect as it does not reflect the correct conversion from liters to milliliters.

2. Convert 0.2 liters to milliliters. What is the equivalent volume?

• A. 20 ml
• B. 200 ml
• C. 2 ml
• D. 2000 ml

Correct answer: B

Rationale: To convert 0.2 liters to milliliters, you need to multiply by 1,000 because there are 1,000 milliliters in a liter. So, 0.2 * 1,000 = 200 milliliters. Therefore, the correct answer is 200 ml. Choice A (20 ml) is incorrect because it represents 0.02 liters, not 0.2 liters. Choice C (2 ml) is incorrect as it represents 0.002 liters. Choice D (2000 ml) is incorrect as it represents 2 liters, not 0.2 liters.

3. What is the equivalent temperature in Kelvin if the temperature is measured at 25 degrees Celsius?

• A. 298.15 K
• B. 273.15 K
• C. 250 K
• D. 25 K

Correct answer: A

Rationale: The correct answer is A: 298.15 K. The conversion from Celsius to Kelvin is K = C + 273.15. Therefore, 25°C is equivalent to 298.15 K, as 25 + 273.15 = 298.15. Choice B, 273.15 K, is the freezing point of water in Kelvin, not the equivalent of 25°C. Choice C, 250 K, and Choice D, 25 K, are incorrect conversions and do not align with the correct formula for converting Celsius to Kelvin.

4. How many grams are in 5 kilograms?

• A. 50 grams
• B. 500 grams
• C. 5000 grams
• D. 5 grams

Correct answer: C

Rationale: To convert kilograms to grams, you need to multiply by 1000 because there are 1000 grams in a kilogram. Therefore, 5 kilograms x 1000 grams/kilogram = 5000 grams. Choices A, B, and D are incorrect because they do not correctly convert kilograms to grams.

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.
