Vapor pressure
The process of bubbles escaping the surface of a heated liquid is called boiling. It happens when the liquid reaches its boiling point and the vapor pressure equals the atmospheric pressure, causing bubbles to form and rise to the surface.
When boiling ethanol, the gas inside the bubbles is mainly ethanol vapor along with some air. Ethanol vapor is formed as the liquid ethanol heats up and turns into a gas, creating bubbles that rise to the surface.
Boiling in a liquid occurs throughout the entire volume of the liquid, as the heat energy applied causes the liquid to reach its boiling point temperature, at which the liquid's vapor pressure equals the external pressure. This results in bubbles of vapor forming within the liquid and rising to the surface.
The boiling point of a liquid is the temperature at which its vapor pressure equals the pressure exerted on it by the surrounding environment, typically atmospheric pressure at sea level. At this temperature, bubbles of vapor form within the liquid and rise to the surface, causing it to boil and change state from a liquid to a gas.
when any liquid BOILS the bubbles just contain the same substance, but just as a gas.now why did I put 'boils' in capitals?you know if you boil water there are tiny bubbles already forming before it is actually boiling. these are the gasses which were dissolved in the water.

Boiling occur in the entire volume of the liquid.
Dissolved air bubbles out of the water, as the boiling point of water is reached, water vapour starts to form inside the liquid in the form of bubbles
The process you are describing is called boiling. Boiling occurs when the vapor pressure of a liquid equals the atmospheric pressure, causing bubbles of vapor to form within the liquid.
This temperature is called the boiling point, and indicates the temperature at which a liquid will assume a gaseous state, given the addition of the heat of vaporization.That is the boiling point.
When boiling ethanol, the gas inside the bubbles is mainly ethanol vapor along with some air. Ethanol vapor is formed as the liquid ethanol heats up and turns into a gas, creating bubbles that rise to the surface.
When a substance reaches its boiling point, it undergoes a phase transition from a liquid to a gas. At this temperature, the vapor pressure of the liquid equals the pressure of the surrounding environment, allowing bubbles of vapor to form within the liquid, resulting in the substance boiling.

Pressure Cookers raise the boiling point of water. As pressure increases on a liquid, so does the boiling point. This is due to the fact that a liquid will not boil until the vapor pressure of the liquid is equals the environmental pressure surrounding the liquid. Think of it essentially as the surrounding pressure holds the substance in liquid form until it has enough energy to escape into gas form.
Boiling is the formation of vapor bubbles inside a liquid. They are not air, but rather some of the liquid that has evaporated. The molecules of the liquid have to have enough energy to break out of the liquid phase and become the vapor. That means the vapor has to push the liquid aside to make the bubble. This happens when the vapor can push back against the atmosphere pushing on the liquid. The boiling point is the temperature where the vapor has enough push to overcome the air pressure. In other words, the boiling point is the temperature where the vapor pressure and the atmospheric pressure are the same. The lower the atmospheric pressure, the lower the boiling point.
