how does conduction,convection or radiation help in the working of heat convector
Answers
Answer:Heat transfer is the physical act of thermal energy being exchanged between two systems by dissipating heat. Temperature and the flow of heat are the basic principles of heat transfer. The amount of thermal energy available is determined by the temperature, and the heat flow represents movement of thermal energy.
On a microscopic scale, the kinetic energy of molecules is the direct relation to thermal energy. As temperature rises, the molecules increase in thermal agitation manifested in linear motion and vibration. Regions that contain higher kinetic energy transfer the energy to regions with lower kinetic energy. Simply put, heat transfer can be grouped into three broad categories: conduction, convection, and radiation.
Explanation:
Convection currents are created when the air above your radiator heats and then cools and is then heated again. This process happens continuously whilst you have your heating on and the current moves the heat around the room making it nice and warm and toasty.
To get even more scientific – heat itself is created through kinetic energy.
When your radiator is heating up the air it’s causing atoms to vibrate at a higher frequency. As more air is drawn through the bottom and over the ‘fins’ of the radiator, atoms continue to vibrate faster and faster and thermal energy is created.
As we are heating gases – in this instance ‘air’ – this process is known as convection
