Understanding Temperature Drop
When an industrial machine is in use, it reaches a temperature of 161°F. After being turned off and left unused for an hour, the temperature decreases to 144°F. To find out how much the machine cooled off, we need to calculate the difference between the initial and final temperatures.
Calculating the Cooling Off
- Initial Temperature (while in use): 161°F
- Final Temperature (after 1 hour): 144°F
To find the cooling off amount, use the formula:
Cooling Off = Initial Temperature - Final Temperature
- Substituting the values:
- Cooling Off = 161°F - 144°F
Performing the Calculation
- Result:
- Cooling Off = 17°F
Conclusion
Thus, the machine cooled off by 17°F, making option 'A' the correct answer. The other options (16°F, 18°F, and 19°F) do not accurately reflect the difference in temperature. This calculation showcases the importance of understanding basic temperature changes in everyday scenarios, especially in industrial contexts where equipment efficiency is crucial.
