A. 36 to 46 degrees Fahrenheit
B. Greater than 30 degrees Celsius
C. 2 to 8 degrees Celsius
D. 15 to 30 degrees Celsius

Answer :

Final answer:

The correct answer for storing an item at room temperature is d. 15 to 30 degrees Celsius, which fits within the typical ambient temperature range considered comfortable for human beings.

Explanation:

When discussing the concept of room temperature, it is important to recognize that it generally refers to a range of temperatures comfortable for humans. While the precise definition can vary, room temperature is often used interchangeably with ambient temperature, which is generally considered to be around 20-25 degrees Celsius (68-77 degrees Fahrenheit). Therefore, the correct answer for storing an item at room temperature is d. 15 to 30 degrees Celsius. This range is broad enough to account for regional and situational differences in what might be considered room temperature.

To convert Fahrenheit to Celsius, we use the formula: C = (F - 32) * 5/9. For example, to conserve energy, room temperatures might be kept at 68.0°F in the winter and 78.0°F in the summer. These temperatures would convert to approximately 20.0°C and 25.6°C, respectively, fitting within the standard room temperature range.
