Excess Pressure Inside a Drop and a Bubble01:13

Excess Pressure Inside a Drop and a Bubble

1.8K
The shape of a small drop of liquid can be considered spherical, neglecting the effect of gravity. This drop can further be considered as two equal hemispherical drops put together due to surface tension. The forces acting on the spherical drop are due to the pressure of the liquid inside the drop, the pressure due to air outside the drop, and the force due to the surface tension acting on the two hemispherical drops.

Imagine adding a small amount of sugar to a glass of water, stirring until all the sugar has dissolved, and then adding a bit more. You can repeat this process until the sugar concentration of the solution reaches its natural limit, a limit determined primarily by the relative strengths of the solute-solute, solute-solvent, and solvent-solvent attractive forces. You can be certain that you have reached this limit because, no matter how long you stir the solution, undissolved sugar remains. The...

The relative amounts of reactants and products represented in a balanced chemical equation are often referred to as stoichiometric amounts. However, in reality, the reactants are not always present in the stoichiometric amounts indicated by the balanced equation.

Carbonation is a process used to dissolve carbon dioxide gas in a liquid, commonly used in the production of carbonated beverages. Achieving efficient carbonation requires careful control of temperature, pressure, and flow conditions. By adjusting these parameters, carbonation efficiency can be maximized, producing a higher concentration of CO2 in the liquid.
Temperature is a key factor in CO2 solubility. In this case, the CO2 gas and the liquid are cooled to 20°C. Lower temperatures...

Carbonation Shrinkage01:24

Carbonation Shrinkage

Atmospheric CO2 penetrates the concrete's pores and, in the presence of moisture, forms carbonic acid, which then reacts with calcium hydroxide in the hydrated cement, forming calcium carbonate. This process reduces the concrete's volume and is termed carbonation shrinkage.
The concrete's permeability is slightly reduced as calcium carbonate produced during the reaction fills its pores. Furthermore, its strength is slightly enhanced as the water released during the reaction...

Area of Science:

  • Physics
  • Materials Science
  • Surface Chemistry

Background:

  • Large bubbles are crucial for studying 2D turbulence and soap systems in physics.
  • Bubble artistry and performances also rely on stable foam films.
  • Existing recipes lack a scientific basis for optimizing bubble stability.

Purpose of the Study:

  • To identify essential physical ingredients for creating stable soap films and bubbles.
  • To develop an effective recipe for long-lasting bubbles.
  • To bridge the gap between scientific understanding and practical bubble-making.

Main Methods:

  • Controlled experiments were designed to assess bubble generation ease.
  • Bubble stability was measured in solutions with varying ingredient concentrations.
  • Ingredients were systematically added to bubble artist recipes to isolate their effects.

Main Results:

  • Excessive surfactant concentration negatively impacts bubble stability.
  • Long, flexible polymer chains are vital for facile bubble formation.
  • Glycerol significantly enhances bubble longevity by inhibiting evaporation.

Conclusions:

  • An optimized bubble recipe requires careful control of surfactant levels.
  • Incorporating polymers and glycerol leads to more stable and easily generated bubbles.
  • The findings provide a scientific foundation for bubble creation in both research and art.
