Given that spaghetti and water were heated.
To find which will cool faster.
Step-by-step explanation:
A substance gets cool down in a room due to the exchange of temperature with the surroundings.
A substance will get cool down if heat flows out of the substance into the surroundings.
For spaghetti, only the upper layer is in contact with the surroundings while for the water, the molecules are free to move, so hotter molecules will come in contact with the surroundings, they will exchange their heat with the surroundings.
After that, these molecules get replaced by much hotter molecules.
This process continues till all the water gets cool.
Thus, water will be more cooler than spaghetti.
