The primary difference between magma and lava is that magma is molten rock beneath the Earth’s surface, while lava is molten rock that erupts onto the surface. What is Magma? Magma is a hot, molten substance that serves as the precursor to igneous rocks. It primarily comprises silicate liquid, but other variations like carbonate and … Read more
The basic difference between gravitation and gravity is that gravitation represents the attractive force that manifests between any two masses, drawing them closer together. It is the force of gravitation that causes objects to be attracted to one another, such as the gravitational pull between the Earth and other celestial bodies, which we commonly refer … Read more
The primary difference between resistance and resistivity is that the resistance of a material increases as its length and temperature rise, while it decreases as the cross-sectional area of the material grows. While resistivity is influenced primarily by the inherent characteristics and temperature of the material. What Is Resistance? Resistance in an electrical circuit is … Read more
The key difference between enthalpy and entropy is that enthalpy refers to the overall heat content within a system, whereas entropy characterizes the level of disorder or randomness within that system. What Is Enthalpy? Enthalpy serves as a crucial thermodynamic property that quantifies the total heat exchange within a system. According to the First Law … Read more
The key difference between alternator and generator is that an alternator transforms mechanical energy into AC electrical power, while a generator is a mechanical apparatus that converts mechanical energy into either AC or DC electrical power. What is Alternator? An alternator is an electromechanical device that transforms mechanical energy into alternating current (AC) electrical energy. … Read more
The primary difference between reflection and refraction is that reflection occurs when light bounces off a surface in a plane, while refraction is the phenomenon where light changes direction as it passes through a material, leading to its bending. What is Reflection? Reflection is when light, sound, heat or an object bounces back to its … Read more
The major difference between watt and volt is that watt measures the rate at which electrical work is done when a current of one ampere flows across a one-volt potential difference. Rather volt represents the potential difference between two points in a conductor, What is Watt? A watt is a unit of power used to … Read more
The primary difference between stress and pressure is that pressure is the measure of force applied per unit area, whereas stress is the force per unit area experienced by a material. What is Stress? Stress arises when an external force is applied to a material, causing it to resist changes in shape or deformation by … Read more
The primary difference between convex lens and concave lens is that a convex lens converges light rays and focuses them to a point, while a concave lens diverges light rays, spreading them apart. What is Convex Lens? A convex lens is a type of optical lens that is thicker in the center and thinner at … Read more
The key difference between two-stroke and four-stroke is that a 4-stroke engine completes one power stroke in four stages, which corresponds to two full revolutions of its crankshaft, whereas a 2-stroke engine accomplishes a power stroke in two stages, equivalent to one complete revolution of its crankshaft. What is Two Stroke? In a 2-stroke engine, … Read more
