Intensive properties of matter remain constant regardless of the amount of substance present, while extensive properties depend on the amount of substance. For example, temperature is an intensive property because it is independent of the mass or volume of a substance, whereas mass and volume are extensive properties because they increase with the amount of … Read more

Angular impulse, a vector quantity arising from the change in angular momentum of a rigid body about a fixed axis, plays a crucial role in rotational dynamics. Angular momentum, the rotational analogue of linear momentum, measures the rotational inertia of an object about an axis. These two concepts are closely intertwined with the principle of … Read more
Point source pollution refers to contaminants originating from a single, identifiable discharge point, such as a pipe, ditch, or industrial facility. These pollutants enter water bodies directly and are often associated with industrial activities, wastewater treatment plants, or agricultural runoff. Point source pollutants can have a significant impact on water quality, affecting aquatic life, human … Read more
The interplay between vapor pressure and atmospheric pressure governs the physical behavior of liquids and gases. Vapor pressure represents the pressure exerted by the vapor phase of a liquid, while atmospheric pressure denotes the force exerted by the weight of the air column above a point. The relationship between these two entities is crucial for … Read more
