A hot cup of coffee loses heat faster than a warm cup Why doesnt the hot cup reach room temperature before the warm cup?
Teresababe92
The hot cup loses heat faster, but only until it becomes a warm cup itself. Then it loses heat as the warm cup did at the beginning. However, by this point, the hot cup is warm, but the warm cup is now cooler too. Therefore, the warm cup will still become room temperature first.
