For instance, I make myself some hot coffee and I want to turn it to iced coffee. Stirring it seems to cool it down much faster than letting the ice just sit in the coffee, however, from what I have read, stirring the ice melts the ice faster and more even though it cools it down faster. Why? Is this even correct?
Also, would the ice just sitting in the hot coffee melt roughly the same amount as the stirred once the coffees reaches the desired cold temperatures? Idk we can make one up, coffee from 160°f to 40°f, I guess. I also generally fill my coffee cup completely with ice as I’m sure the amount of ice changes this.
I hope this makes sense and I tagged the question correctly. Thank you,

A thermal gradient is a location where the temperatures change. In a glass of water with ice, the gradient changes suddenly between the ice and the water around it. The gradient likes to be smoother, so the water around the ice becomes colder and the ice next to the water becomes warmer. By stirring, the water is mixed to a more consistent temperature, causing a steeper thermal gradient around the ice.
