For example:

• Charcoal adsorbing gases
• Silica gel adsorbing moisture
• Activated carbon used in water purification

Adsorption is a surface phenomenon and mainly occurs on the surface layer of materials.

Types of Adsorption

Physical Adsorption (Physisorption)

Physical adsorption occurs because of weak intermolecular forces such as Van der Waals forces.

Characteristics:

• Reversible process
• Low heat of adsorption
• Occurs at low temperatures
• Forms multiple layers

Example:
Adsorption of gases on activated charcoal.

Chemical Adsorption (Chemisorption)

Chemical adsorption involves the formation of chemical bonds between the adsorbate and adsorbent.

Characteristics:

• Irreversible process
• High heat of adsorption
• Highly specific
• Usually forms a single layer

Example:
Adsorption of hydrogen on metals like nickel.

Factors Affecting Adsorption

Nature of Adsorbent : Porous substances with larger surface areas show better adsorption capacity.

Surface Area : Greater surface area increases adsorption because more space becomes available for adsorbate molecules.

Pressure : For gases, adsorption generally increases with increasing pressure.

Temperature : Physical adsorption decreases with increase in temperature, while chemisorption may increase initially.

Adsorption Isotherms

Adsorption isotherms explain the relationship between pressure and adsorption at constant temperature.

Freundlich Adsorption Isotherm

The Freundlich equation is:

xm=kp1/n\frac{x}{m} = kp^{1/n}mx​=kp1/n

Properties of Electric Charge

Electric charge is a fundamental property of matter responsible for electrical interactions between objects. The main properties of electric charge include attraction and repulsion between charges, conservation of charge, and quantization of charge. Like charges repel each other while unlike charges attract each other. Electric charge can neither be created nor destroyed; it can only be transferred from one object to another. Charge always exists in discrete quantities and is measured in Coulombs (C).

Methods of Charging

Objects can be charged through different methods such as friction, conduction, and induction. Charging by friction occurs when two objects are rubbed together, causing transfer of electrons. Charging by conduction happens through direct contact between a charged and neutral object, allowing charge transfer. Charging by induction is a method where a charged object induces charge separation in another object without direct contact. These methods help explain the behavior of static electricity in everyday life.

Coulomb’s Law

Coulomb’s Law explains the force between two stationary electric charges.

Important Points:

• Force is directly proportional to the product of charges
• Force is inversely proportional to the square of the distance between them
• The force acts along the line joining the charges

Electrostatic force can either be attractive or repulsive depending on the nature of charges.

Electric Field

An electric field is the region around a charged object where another charge experiences force. Electric field strength depends on:

• Magnitude of charge
• Distance from the charge
• Medium surrounding the charge

Electric field lines help represent the direction and strength of electric fields.

Electric Potential

Electric potential refers to the work done in bringing a unit positive charge from infinity to a point in the electric field.

The SI unit of electric potential is Volt (V).

Applications of Electrostatics

Electrostatics has several practical applications in modern science and technology, including:

• Electrostatic precipitators
• Inkjet printers
• Photocopiers
• Spray painting

Understanding the difference between concave and convex mirrors is a fundamental concept in physics, especially for school students and competitive exams. At Vision Academy – Science Academy in Kalyan, we simplify complex science topics to help students build strong conceptual clarity.

What is a Mirror?

A mirror is a smooth, polished surface that reflects light and forms images. Mirrors are mainly classified into:

• Concave Mirrors
• Convex Mirrors

What is a Concave Mirror?

A concave mirror is a curved mirror that bends inward, similar to the inside surface of a spoon. It is known as a converging mirror because it brings parallel light rays together at a focal point. Depending on the position of the object, a concave mirror can form both real and virtual images, which may be magnified, diminished, or of the same size. Due to its ability to focus light, it is widely used in applications like shaving mirrors, vehicle headlights, and solar devices.

What is a Convex Mirror?

A convex mirror is a curved mirror that bulges outward, like the back surface of a spoon. It is called a diverging mirror because it spreads light rays away from the surface, forming images that are always virtual, upright, and smaller than the actual object. Convex mirrors provide a wider field of view, making them ideal for safety and surveillance purposes such as rear-view mirrors in vehicles, security mirrors in shops, and road safety mirrors.
