If Takashi is standing on the equator and Fariha is standing on the North Pole, both holding a cup of hot tea, whose tea will cool down faster, and why?

Provide a very brief response.
Fariha's tea will cool down faster because the surrounding environment at the North Pole is much colder than at the equator. This higher temperature difference between Fariha's hot tea and the cold polar air will result in a faster rate of heat transfer from the tea to the surrounding environment. Heat transfer, through convection, conduction, and radiation, occurs quicker when there is a large temperature gradient. Since Takashi is at the equator, where the climate is warmer, the temperature gradient between the hot tea and the surrounding air is less, resulting in a slower rate of cooling.
