I mentioned I was a car guy so this is the best car example I can think of for cars, a radiator taking in cold air which runs through the system, transferring the unwanted heat in the liquid in the radiator to the cold air, making it hot air and spitting that out of the system. The most common example in the real world is a pot with water in it, resting on a burner. The heat made from the burner is quickly transferred to the pot and then heating up the water. The thing that separates this from conduction is that the molecules directly touching the pot receive the energy transferred, and move away quickly, only to be quickly replaced by another molecule that lacks this energy, and moving in a continuous cycle. Continuing on the concrete surrounding the pool scenario mentioned earlier, you decide you want to get into the pool, but it is so big that it has not received enough energy radiated from the sun, so you turn on the gas powered pool heater. Convection does not just deal with a flame to achieve, you could also see it by just simply observing an ice cube melt in your hand, because your hand literally is transferring your body heat to the ice cube. Convection can deal with all physical states, so referring back to the swordsmith example, and are done heating up the …show more content…
The most common example of radiation is the sun. The sun radiates heat in the form of light to the earth. So like I mentioned earlier the pool, it needed to be heated by convection because the sun did not radiate enough energy to the pool. Just like the pool, the intensity of heat that is felt is determined by the earth’s position and how close it is to the sun, which is why we have seasons. The distance of the earth from the sun determines the magnitude of heat. We can also experience this by getting close to a light bulb, the closer you get the hotter it feels. It does not just apply to light production, although that is where it is most common, you can also see it in cars. Say you drive your car for a while, if you open the engine bay, you can literally feel the heat radiating from your car. If it is intense enough, you may not even need to open the hood to experience the heat from the engine. You can also observe radiation when the sun is hot and radiates heat to pavement, heating it up and making the pavement radiate heat and you can even see light bend on pavement if it is hot enough. The simplest example of radiation is holding a beaker of liquid over a Bunsen burner, not in direct contact with the flame. The combustion of fuel from the Bunsen burner releases
