Heat transfer keeps your food warm in the microwave

The reason food remains warmer in the microwave compared to the counter is rooted in science, specifically a phenomenon known as heat transfer. When two objects are in close proximity, their temperatures tend to equalize. This means that cold air seeks to enter hot food, while the heat from the food aims to warm the surrounding cold air. On the counter, food is exposed to a larger environment, allowing heat to escape quickly as it tries to warm the air around it.
In contrast, a microwave has significantly less surrounding space, and since the hot food occupies most of that area, the heat transfer is limited. The temperature difference between two containers of food is minimal, which means heat energy doesn't dissipate as rapidly. So, the next time you find yourself in a hurry after picking up fast food, consider placing it in the microwave to keep it warm without needing to reheat it later.
