The temperature of the refrigerator should always be at 60 degrees.

Question

BlackTom AI · Accepted Answer

Refrigerators should be kept at or below 40°F (4°C) to slow bacterial growth; therefore the statement that it “should always be at 60 degrees” is false.

1) Relevant knowledge points and concepts
- Safe refrigeration: Food-safety authorities (USDA/FDA) recommend refrigerator temperature at or below 40°F (4°C); ideal is often 35–38°F (1.7–3.3°C).
- Danger zone: Bacterial growth is rapid between 40°F and 140°F (4°C–60°C). Keeping food below 40°F greatly reduces pathogen multiplication.
- Units matter: “60 degrees” could mean 60°F (room-warm for perishables) or 60°C (extremely hot). Both are inappropriate for refrigeration.

2) Step-by-step reasoning
- If 60 degrees means 60°F: compare to the safe limit 40°F. 60°F is 20°F higher than the recommended maximum for refrigeration, so perishable foods would be kept in the danger zone and spoil or permit pathogen growth.
- If 60 degrees means 60°C: that equals 140°F (see conversions below) and would cook or destroy food rather than refrigerate it — obviously not a refrigerator setting.

3) Calculations and conversions (intermediate steps shown)
- Convert 60°F to °C: (60 − 32) × 5/9 = 28 × 5/9 = 140/9 ≈ 15.6°C. (Too warm for safe refrigeration.)
- Convert 60°C to °F: (60 × 9/5) + 32 = 108 + 32 = 140°F. (Extremely hot; not refrigeration.)

4) Why the correct answer is correct
- A refrigerator set at 60°F (≈15.6°C) would leave perishable foods in the bacterial danger zone, increasing risk of foodborne illness. 60°C (140°F) is a hot-holding/cooking temperature, not refrigeration. Thus the statement is incorrect in any reasonable interpretation.

5) Why the other option is incorrect
- “True” would assert that 60 degrees is the proper refrigerator temperature; that is incorrect because it contradicts established food-safety guidelines (refrigerators should be ≤40°F/4°C).

Conclusion: The correct choice is False, which matches the provided answer.

The temperature of the refrigerator should always be at 60 degrees.Single choice
