On a sunny day in the tropic, the air temperarure changes from 15 degrees celcius to 30 degrees celsius at noon. on a winter day in the nothern hemisphere, the air temperature changes from 0degree fareinheit at dawn to 15 degrees fahrenheit by midafternoon. ehich change is greater and why?

To solve this problem it is necessary to take into account the concepts of conversion of Temperature Units.

In the international system, the centigrade degree is equivalent to

For Sun day we have that the total change in Temperature is given by

Initial temperature

Final Temperature

Change in Temperature

For winter day we have

Initial temperature

Final Temperature

Change in Temperature

Therefore the change in sunny day is grater that change in Winter day

i think the answer would be b
