Question

On the coldest night in Vostok Station, Antarctica, the temperature dropped from 0°C to −24°C in 4 hours.

What is the average temperature change per hour?

Enter your answer in the box.

[___] ºC ?

Answer 1

-6 C* is the answer.

Answer 2

Average of any physical quantity is defined over an interval of time. Therefore, the average temperature for this case should be calculated as follows:

Average temperature = (final temp. - initial temp.) / total time
Average temperature = (-24 - 0) / 4
Average temperature = -6°C

Hope this answers the question. Have a nice day.
