Examples of Absorption in Daily Life: Let’s Find Out

Wanna know what are the top 6 examples of absorption in daily life? If yes, then you are at the right place at the very right time. But before going ahead, let me tell you what is absorption anyway. By definition, Absorption is a process during which a substance completely gets dissolved or absorbed into the other substance.

In other words, it refers to the uptake and assimilation of substances into another substance, often leading to remarkable results. The substance that gets absorbed is known as the Absorbate. On the flip side, the substance that absorbs is known as the Absorbent. Just because the Absorbate is taken up by volume, not by surface, the process of Absorption is a Bulk Phenomenon.

From cleaning spills to medical applications, absorption plays a vital role in our daily routines. In this exclusive article, we will delve into real-life examples of absorption, highlighting its practical applications and significance. By understanding these examples, we can gain insight into how absorption contributes to our daily lives and its role in various industries and processes.

Examples of Absorption in Daily Life

  • Sponge Absorbing Water
  • Water Absorption in Plants
  • Absorption of Sunlight by Solar Panels
  • Absorption of Sound Waves
  • Paper Absorbing Ink
  • Oil Absorption in Cooking

Sponge Absorbing Water

Sponges are widely recognized for their ability to absorb and retain water. They are highly porous materials made up of interconnected tiny air pockets and fibers. When a dry sponge comes into contact with water, several processes occur simultaneously to facilitate absorption.

Firstly, the sponge’s porous structure allows it to create a large surface area. This increased surface area enhances the sponge’s ability to interact with the water molecules, promoting quick and efficient absorption.

The capillary action within the sponge’s fibers draws the water in and distributes it throughout the material, preventing localized saturation. The absorbed water can then be squeezed out when needed, making sponges a valuable tool for cleaning spills and wiping surfaces in our homes.

Water Absorption in Plants

Plants absorb water and essential minerals from the soil through their root systems. This process primarily relies on osmosis, a passive movement of water across a semipermeable membrane from an area of lower solute concentration (the soil) to an area of higher solute concentration (the plant’s root cells).

The roots’ structure, including root hairs and root cap cells, enhances the plant’s ability to efficiently absorb water and nutrients. Once absorbed, water travels through the plant’s vascular system, reaching various parts of the plant and sustaining its growth and metabolism. To sum up, the process of absorption is vital for plants to absorb water efficiently from their surroundings, enabling their growth and survival.

Absorption of Sunlight by Solar Panels

We all know how solar panel works…!!! Solar panels harness the power of the sun through a process known as the photovoltaic effect. Photovoltaic cells within the solar panels are composed of semiconductor materials, such as silicon, which have the ability to absorb photons (particles of light).

When sunlight strikes the surface of the solar panel, photons are absorbed by the semiconductor material, exciting its electrons. This creates a flow of electric current, generating usable electricity. Solar panels have gained popularity as a sustainable and renewable energy source, contributing to the reduction of greenhouse gas emissions.

Absorption of Sound Waves

Sound absorption is a crucial aspect of acoustic engineering. Certain materials, known as acoustic absorbers, are designed to reduce sound reflections and echoes in indoor spaces. These materials include Acoustic panels, foam, fabric-covered surfaces, etc.

As sound waves encounter these materials, they penetrate their surfaces and are converted into small amounts of heat energy due to friction and viscous losses. By strategically placing acoustic absorbers in rooms, we can create a more comfortable and balanced acoustic environment.

To put it differently, in spaces like recording studios, theaters, and offices, acoustic absorption enhances the overall sound quality and clarity in spaces like recording studios, concert halls, theaters, and offices.

Paper Absorbing Ink

The absorption process is crucial for the paper to absorb ink effectively. Paper’s ability to absorb ink makes it a versatile medium for written communication and artistic expression. Paper is made from cellulose fibers, which have a porous structure that readily absorbs liquids like ink.

On the other hand, Ink consists of pigments and solvents that allow for fluid application. So, when we write with a pen or print using an inkjet printer, the liquid ink is deposited onto the paper’s surface. The paper fibers absorb the ink, allowing it to dry quickly and become a permanent part of the paper.

Oil Absorption in Cooking

As oil is heated in a pan or deep fryer, the food being cooked absorbs some of the oil. Technically, oil absorption occurs as a culinary technique to enhance flavors and textures. For example, the crispiness of fried foods is attributed to the oil absorbed during cooking.

When food items such as vegetables or meat are immersed or cooked in oil, the oil is absorbed into their porous structures. This absorption can result in improved taste, moisture retention, and the development of desirable textures in cooked food.

Not to mention, proper temperature control and choosing the right cooking oils are essential to minimize excessive oil absorption and maintain a healthy diet.

Some Other Applications of Absorption in Real Life

Apart from the above-mentioned one, I am also mentioning some here for your reference.

  • Absorption of Colors by Art Materials
  • Absorption of Moisture by Hair and Skin
  • Absorption of Dyes in Textiles
  • Absorption of Moisture by Desiccants
  • Absorption of Medication by the Body
  • Absorption in Refrigeration, etc.

I am a mechanical engineer by profession. Just because of my love for fundamental physics, I switched my career, and therefore I did my postgraduate degree in physics. Right now I am a loner (as ever) and a Physics blogger too. My sole future goal is to do a Ph.D. in theoretical physics, especially in the field of cosmology. Because in my view, every aspect of physics comes within the range of cosmology. And I love traveling, especially the Sole one.
