Energy is the ability to do work. It exists in various forms, like kinetic, potential, thermal and chemical. Energy powers everything, from machines to living beings. It cannot be created or destroyed, only transformed. Renewable sources, like solar and wind, ...
Heated refers to the process of increasing the temperature of an object or substance. When something is heated, its particles gain energy, causing them to move faster. This can lead to changes in physical properties such as expansion or phase ...
A tungsten filament is a thin wire made of tungsten metal used in light bulbs and other electrical devices. Tungsten has a high melting point and excellent conductivity, making it ideal for producing light when heated. It can withstand high ...
A temperature scale is a system for measuring temperature. The most common scales are Celsius, Fahrenheit, and Kelvin. Celsius is based on the freezing and boiling points of water, Fahrenheit on the freezing and boiling points of water in Fahrenheit ...
Vapour is the gaseous state of a substance that is typically liquid or solid at room temperature. It forms when the substance evaporates or sublimates. Vapour can exist below its boiling point and can be seen as mist or steam ...
Radiation is the transfer of energy through electromagnetic waves or particles. Unlike conduction and convection, radiation does not require a medium and can occur in a vacuum. It includes visible light, infrared radiation, ultraviolet rays, and other electromagnetic waves. Objects ...
Energy is the ability to do work or cause change. It exists in different forms such as kinetic potential thermal chemical and nuclear. Energy can be transferred or transformed but it cannot be created or destroyed. It plays a vital ...
Radiating power refers to the amount of energy emitted by a body per unit area per unit time due to its temperature. It is governed by Stefan-Boltzmann law and depends on the body’s temperature and surface properties. A hotter object ...
Energy is the capacity to do work or produce change. It exists in forms like kinetic, potential, thermal, chemical, and nuclear. Energy transforms but cannot be created or destroyed (law of conservation). It’s essential for life, powering everything from biological ...
