The amount of temperature needed to fall to return to the original temperature of 33°F is 7°F.
Temperature
- A physical quantity that tells about the degree of hotness or coldness is called temperature.
- Temperature is measured on two units which are °C (degree Celcius) and °F (degree Fahrenheit).
The temperature at different parts of a day
At 6:00 A.M. the temperature was 33°F.
The temperature by noon had increased 10°F.
And by 3:00 P.M. it had increased 12°F.
So, the temperature at 3:00 P.M. is,
= 33°F + 10°F + 12°F
= 55°F
Also, the temperature decreased by 15°F at 10:00 P.M.
So, the final temperature is,
= 55°F - 15°F
= 40°F
The temperature needed to fall to return to the original temperature of 33°F is,
= 40°F - 33°F
= 7°F.
Hence, a temperature of 7°F is needed to fall for it to return to its original temperature of 33°F.
