Physics

Every scientific explanation is realized with the aid of a number of physical quantities — each expresses a special meaning and significance in that context. By definition, a physical quantity is measurable and quantifiable physical property that carries unique information with it. Based on the dependency nature, such quantities can be of two types — fundamental and derived. A fundamental quantity is one that is independent of other properties; while,

Difference between fundamental unit and derived unit

Physics

Every physical “matter” intrinsically consists of one or more “properties” (such as mass, weight, length, velocity, temperature, current, etc.). By definition, every property of a matter is measurable and quantifiable. Measurement of a property can be carried out with suitable instrument. However, to quantify the measured result, a “magnitude” along with its “unit” is required to present. By definition, a unit of measurement indicates “a standardized and well-defined magnitude of

Difference Between Mass and Weight

Physics

By definition, a “matter” is any substance that has non-zero mass and occupies certain amount of space based on its volume. The amount of matter contained in a physical body is known as “mass”. Mass is a fundamental extensive property of every matter. A matter can exists in any one of four different states/forms, namely solid, liquid, gas, and plasma. Irrespective of its state, the Earth attracts every matter towards

Difference between open system, closed system and isolated system
Thermodynamics

Thermodynamics

Thermodynamic system is defined as a definite quantity of matter or a region in space upon which attention is concentrated for the analysis of a problem. Everything in this universe external to the system is called surroundings. The system is separated from the surroundings by the system boundary. Every interaction between the system and surroundings occurs across the boundary. There are two distinct ways of interaction between system and surroundings,

Thermodynamics

Thermodynamic system refers to a definite quantity of matter or a specific region in space upon which attention is concentrated for the analysis of a problem. Each thermodynamic system has certain characteristics by which its conditions can be described. Such characteristics are known as thermodynamic properties. Properties are always macroscopic in nature (i.e. observable or sensible with simple instruments). Properties are also point functions (i.e. property has a definite value

Thermodynamics

Thermodynamics

For the analysis of any thermodynamic problem, the concerned matter or a region is considered as the system. By definition, thermodynamic system is defined as a definite quantity of matter or a region in space upon which the attention is focused for the analysis of a problem. Everything in the entire universe external to this system is called the surroundings. The system is separated from the surroundings by a boundary.
