1. How many pounds are in 1 ton?

• A. 1000 pounds
• B. 2000 pounds
• C. 1500 pounds
• D. 2500 pounds

Correct answer: B

Rationale: The correct answer is B: 2000 pounds. A ton is equivalent to 2000 pounds. This is a standard conversion in the imperial system of measurement. Choice A, 1000 pounds, is incorrect as it represents half a ton. Choice C, 1500 pounds, and Choice D, 2500 pounds, are also incorrect as they do not match the correct conversion of 1 ton to 2000 pounds.

2. 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.

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. 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.'

5. 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.
