What is the connection between radiation, convection and management?
radiation, convections and guidance are three different ways to transfer heat. Convections and lines require heat transfer. Radiation transmission of temperature in the form of energy as waves. Although these three heat transfer methods include different principles, all of them can be understood on the basis of heat or thermal energy physics. When the material with a higher temperature comes into contact with a lower temperature material, it flows from warmer to cooler material. This process will continue until these two materials are at the same temperature and have reached the state of thermal balance. Heat is done because the rapidly moving particles of warmer mass transmission to cooler, slower molecules of colder mass. The capacity of the material to make heat depends on its molecular structure and consistency. For example, metals are better heat conductors than wood and solids are better heat conductors than liquids.
convection transmitsHeat on the basis of another principle of particle movement. When particles have a large amount of thermal energy, this energy causes them to move faster and spread so that the material is less dense. The particles in the colder area have less energy and move slowly, leading to greater density. In fluids and gases, this principle leads to cooler areas of material descending to the bottom, while warmer areas rise to the top.
The current consists of a circulation of fluid or gas in this pattern. This is called a convection current. In the atmosphere, for example, the cold air decreases, while the warm air rises and produces circulation.
The third heat transfer method, radiation requires, regardless of particulate interaction, regardless of the interaction. An example is sunlight. The heat from the sun reaches the ground even though it travels the vacuum of the universe. In the case of radiation, there is a thermal energy in the form of waves. It is a type of electromagnetic radiation such as visible light.
atoms absorb energy glowOutline through their electrons that use energy to move to a higher level in the atom. This energy can be re -emitted when the electron falls to the original level. The temperature of the object in the presence of radiation depends on how much energy it absorbs compared to how much it emits, so an object that absorbs more energy than emitts increases the temperature.
