Thermal refers to the heat energy within a system and its transfer due to temperature differences. It involves concepts like heat conduction convection and radiation. Thermal properties include how substances expand or contract with temperature changes. These properties are essential ...
Power is the rate at which work is done or energy is transferred. It is defined as the amount of work done per unit time. The SI unit of power is the watt (W) where 1 watt is equal to ...
A law is a principle that describes a consistent relationship or pattern observed in nature. It is based on repeated experimental evidence and remains universally valid under specified conditions. Laws explain natural phenomena and predict outcomes without exceptions or deviations. Thermal ...
Electromagnetic refers to the interaction of electric and magnetic fields. These fields are interrelated and travel as waves through space. Electromagnetic waves include light radio waves microwaves and X-rays. They play a crucial role in communication and energy transfer. The ...
Phenomena refer to observable events or occurrences that can be studied or analyzed. In science, it refers to natural processes or facts that can be observed, measured, and explained. These can include physical, chemical, or biological events, such as changes ...
Convection is the transfer of heat through a fluid (liquid or gas) by the movement of the fluid itself. When the fluid is heated, it expands becomes less dense and rises. The cooler fluid then sinks to take its place. ...
Thermal conductivity is the property of a material to conduct heat. It depends on the material’s nature temperature and structure. Good conductors like metals have high thermal conductivity while insulators like wood and rubber have low conductivity. The unit of ...
Thermal conduction is the transfer of heat within a substance without the movement of its particles. It occurs due to the transfer of kinetic energy between neighboring molecules or atoms. Metals are good conductors as they have free electrons while ...
Conductivity is the property of a material to allow the flow of heat or electricity through it. Thermal conductivity measures heat transfer, while electrical conductivity measures electric current flow. Good conductors like metals have high conductivity, enabling efficient transfer, while ...
