Stages of Boiling Liquid

The process of boiling involves the conversion of a liquid into a vapor or gas state. There are several stages or steps that occur during the boiling process. Here are the stages of boiling a liquid:

1. Nucleation: This is the initial stage of boiling where small bubbles or nuclei form at the bottom of the container. These bubbles are formed due to the presence of impurities or irregularities on the surface of the container or the liquid itself.

2. Bubble Growth: As heat is applied to the liquid, the bubbles formed during nucleation start to grow in size. The heat causes the liquid to vaporize, and the bubbles rise to the surface. The rate of bubble growth depends on factors such as the temperature, pressure, and properties of the liquid.

3. Bubble Departure: At this stage, the bubbles detach from the surface and rise to the top of the liquid. The buoyancy force overcomes the surface tension, allowing the bubbles to break free and escape into the surrounding atmosphere. This is when the liquid appears to be actively boiling.

It's important to note that the boiling point of a liquid is the temperature at which its vapor pressure equals the atmospheric pressure. At this point, the liquid undergoes a phase change from a liquid to a gas. The boiling point varies depending on the substance and the surrounding pressure.
