Answer: The temperature at the Tarangahan Falls is -6.5°C, and the temperature in the City Proper is 32.3°C. The difference in temperature is:
32.3°C - (-6.5°C) = 32.3°C + 6.5°C = 38.8°C
So, the difference in temperature between the City Proper and the Tarangahan Falls is 38.8°C.
If the air conditioner is set at 24°C, the temperature would likely drop after the morning, assuming that the air conditioner is cooling the air.
