What happens when a liquid boils?
Understand the Problem
The question is asking about the physical process that occurs when a liquid reaches its boiling point. This typically includes changes in temperature, pressure, and the transition of the liquid into vapor.
Answer
A liquid boils when its vapor pressure matches atmospheric pressure, forming vapor bubbles that rise and release gas.
When a liquid boils, it transforms from a liquid phase to a gaseous phase. This occurs when the liquid's vapor pressure equals the atmospheric pressure exerted on it, allowing vapor bubbles to form and rise to the surface, releasing gas.

More Information
Boiling is a crucial process in cooking, industrial applications, and natural phenomena when liquid turns into vapor at its boiling point.
Tips
A common mistake is confusing boiling with evaporation. Evaporation can occur at temperatures below boiling and only happens at the surface.
