Why water bubbles on the stove while boiling but not in the microwave

Boiling water is one of those simple things that hides fascinating science. You see bubbles rising in a pot on the stove, but when you heat water in a microwave, it often stays still. The difference isn’t just about temperature; it’s about how heat spreads and how bubbles form. The bubbles on the stove appear because of hot spots where steam pockets can grow, while microwaves heat water more evenly and suppress those visible bubbles. A study published in the Journal of Chemical Education explains that water heated in a microwave can reach superheated temperatures above 100°C without boiling because of the lack of nucleation sites that trigger vapour formation. Here’s the science behind it and why it matters for safety. When you heat water on a stove, the bottom of the pan gets hott
