Question 1

If normal body temperature is 98.6°F then what is this in degrees Celsius?

Accepted Answer

To convert Fahrenheit to Celsius, we use the formula:
°C = (°F - 32) x 5/9

So, for a normal body temperature of 98.6°F, we have:
°C = (98.6 - 32) x 5/9
°C = 66.6 x 5/9
°C = 37.0

Therefore, the correct answer is D) 37.0°C.

Question 2

The average distance between the Earth and the Moon is 240,000 miles. Express this distance in meters. (1 mi = 1609 m)

Accepted Answer

We can start by converting the distance in miles to meters using the conversion factor given:
240,000 miles x 1609 m/mile = 386,160,000 m
This number is in scientific notation already, so there's no need to convert. Therefore, the answer is 3.9 × 10¹⁸m, which corresponds to choice C.

Question 3

How many inches are in 382.5 cm? (1 in = 2.54 cm)

Accepted Answer

To convert centimeters to inches, divide the number of centimeters by 2.54 (since 1 inch is equal to 2.54 cm). Therefore, 382.5 cm / 2.54 cm/in = 150.6 inches.

Question 4

How many inches are in 382.5 cm? (1 in = 2.54 cm)?

Accepted Answer

To convert centimeters to inches, divide the number of centimeters by 2.54 (since 1 inch is equal to 2.54 cm). Therefore, 382.5 cm / 2.54 cm/in = 150.6 inches.

Question 5

What is the volume of a container that contains 14.3 g of a substance having a density of 0.988 g/cm³?

Accepted Answer

To find the volume, we can use the formula:
Density = Mass/Volume 
Therefore, Volume = Mass/Density
Plugging in the given values:
Volume = 14.3 g / 0.988 g/cm³
Volume = 14.5 cm³ (rounded to one decimal place)
Therefore, the correct answer is (C).

Question 6

Isopropyl alcohol, commonly known as rubbing alcohol, boils at 82.4°C. What is the boiling point in kelvins?

Accepted Answer

To convert Celsius to Kelvin, we add 273.15. Therefore, the boiling point of isopropyl alcohol in Kelvin can be calculated as follows:
82.4 + 273.15 = 355.55 K
Rounded to one decimal place, the answer is 355.6 K.

Question 7

Question 8

Given that 1 inch = 2.54 cm, 1.00 cm³ is equal to

Accepted Answer

To convert cubic centimeters to cubic inches, use the conversion factor (1 inch = 2.54 cm). Therefore, 1 cm³ = (1/2.54)³ in³ ≈ 0.0610 in³.

Question 9

The answer of How many mm³ are in 16.7 cm³? ...

Question 10

The boiling point for liquid helium is 4.0 K. What is the temperature in degrees Fahrenheit?

Accepted Answer

4.0 K = -452.2 °F (using the conversion formula: °F = 1.8(K) - 459.67)
Therefore, the correct answer is A) -452.5°F, which is the closest option to -452.2°F.

Question 11

The boiling point for liquid nitrogen is 77 K. What is the temperature in degrees Fahrenheit?

Accepted Answer

To convert Kelvin to Fahrenheit, use the formula F = (K - 273.15) * 9/5 + 32. Plugging in 77 K gives F = (77 - 273.15) * 9/5 + 32 = -321°F.

Question 12

How many cubic inches are in 1.00 liter? (1 in = 2.54 cm)

Accepted Answer

1 liter = 1000 cm³1 cm = 0.3937 in1000 cm³ = 1000 (0.3937 in)³ = 61.02 in³

Question 13

A large pizza has a diameter of 15 inches. Express this diameter in centimeters. (1 in = 2.54 cm)

Accepted Answer

To convert inches to centimeters, we need to multiply by 2.54. So, 15 inches x 2.54 cm/inch = 38.1 cm. Rounded to the nearest whole number, the diameter of the large pizza in centimeters is 38 cm. Therefore, the correct choice is A).

Question 14

If a patient in the hospital is running a temperature of 39.5°C, what is this in degrees Fahrenheit?

Accepted Answer

To convert Celsius to Fahrenheit, use the formula F = C * 9/5 + 32. For 39.5°C, it's 39.5 * 9/5 + 32 = 103.1°F.

Question 15

If the temperature is 38.0°F then what is the temperature in kelvins?

Accepted Answer

To convert Fahrenheit to Kelvin, first convert Fahrenheit to Celsius by subtracting 32 and multiplying by 5/9, then add 273.15. For 38.0°F: (38.0-32) * (5/9) + 273.15 = 3.33 + 273.15 = 276.48, which rounds to 276.5 K.

Question 16

Acetone, which is used as a solvent and as a reactant in the manufacture of Plexiglas®, boils at 56.1°C. What is the boiling point in degrees Fahrenheit?

Question 18

Dry ice (carbon dioxide) changes from a solid to a gas at -78.5°C. What is this temperature in °F?

Accepted Answer

To convert from Celsius to Fahrenheit, use the formula F = (C × 9/5) + 32. For -78.5°C, F = (-78.5 × 9/5) + 32 = -109.3°F, which rounds to -109°F.

Question 19

What is the volume in milliliters of a 32.0 fl oz can of juice? (1 fl oz = 29.6 mL)

Accepted Answer

32.0 fl oz * 29.6 mL/fl oz = 947.2 mL
Therefore, the volume in milliliters of a 32.0 fl oz can of juice is 947 mL (rounded to the nearest milliliter).

Question 20

Express 122.0°F in °C.

Accepted Answer

To convert Fahrenheit to Celsius, use the formula: $°C = (°F - 32) \times \frac{5}{9}$. Applying this to 122.0°F: $°C = (122.0 - 32) \times \frac{5}{9} = 90.0 \times \frac{5}{9} = 50.0°C$.
