What Are The Examples Of Convection?
You might have learned examples of Convection during your schooling. Today, we will discuss them in detail and also add a few more examples to them. While talking about the process of Convection, refers to the process of transfer of heat or energy through fluid from high temperature to low temperature. For instance, take an iron rod and hold one end in your hand, and put the other end in the fire. After a few minutes, you may feel the heat in the rod. Why did this happen? This happened because of the process of conventions. In short, convection is a method of heat transfer. Well, below we will discuss it in detail. Let’s get started to know the examples of convection.
What Is The Convection?
Convection is a process in which heat gets transferred from a higher temperature to a lower temperature. It is one of the three main types of heat transfer, the other two types are radiation and conditions. Conduction refers to the transfer of heat between bodies that are physically attached. Whereas, radiation is a process in which energy is emitted in the form of electromagnetic waves. A real-life example of conventions is the frying pan.
The application of conventions includes boiling water, radiator, ice melting, steaming cup of hot tea, etc.
Now, you know what is the process of convection. Let’s take a look at some examples of convection heat transfer.
What Are The Examples Of Convection?
Examples of convection are,
- Breeze
- Boiling water
- Blood Circulation in Warm-Blooded Mammals
- Radiator
- Air Conditioner
- Hot Air Popper
- Refrigerator
- Hot Air Balloons
- Hot Beverage
- Rainfall and Thunders
There are multiple examples of convection in real life. Keep reading, below we will explain by giving examples of convection in detail.
10 Examples Of Convection
There are more than 3 examples of convention, here we have selected some important among them. Let’s have a detailed analysis of all examples of convection energy.
1. Breeze
One of the common examples of convection in science is the breeze. You might observe that, in the afternoon, the space of the land near the sea is warmer as compared to the evening. Convection causes air closer to the earth’s surface to heat up and rise. This warm air near the ground is easily displaced by cooler air, resulting in a “sea breeze.”
2. Boiling water
One of the great examples of convection in cooking is boiling water. How? The cold water below is heated by the energy of the burner and rises. As you heat the bottom of the pot, you may see the hot water rise and the cold water rushes in to replace it, which results in motion in a circular fashion. This is nothing but the process of convection.
3. Blood Circulation in Warm-Blooded Mammals
The human heart is a pump, and circulation in the human body is an example of forced convection. Why forced convection? Because, in this process, your heart is forcing blood to flow. The cold water below is heated by the energy of the burner and rises.
4. Radiator
The radiator works on the principle of conventions. In radiators, the healing element is placed at the bottom. The cold air, being dense, sinks and it takes into the radiator. It is warmed and released. The hot air replaces the gap left by the cold air. Therefore, a convection current is set up. This is an example of a situation or object that uses convection currents.
5. Air Conditioner
In summer or any other season people use air-conditioners constantly. The process of cooling air in an air-conditioner employs the very principle of convection. Cold air is exhausted from the air conditioning system. Now, this cold air is denser than warm air, so it sinks. Because the warm air is less dense, it rises and is sucked in by the air conditioner’s exhaust fan. This is one of the amazing examples of convection in a house.
6. Hot Air Popper
A hot air popper is used to make instant pop-corns, it also uses the principle of convection. In the hot air popper, extremely hot air is used to make popcorn. There are fans, vents, and heating elements. When the popper is on, a fan blows air through the vents and onto the heating element. The heating element then becomes warm and makes the air hot. Above the heating element, the popcorn kernels are placed. The kernels are heated when the hot air rises, therefore resulting in the popping of the kernels.
7. Refrigerator
The principle of operation of a refrigerator is very similar to that of an air conditioner. For refrigerators, the freezer is on top. In the refrigerator, the cool air sinks and therefore keeps the lower part of the fridge cool.
8. Hot Air Balloons
Why are hot air balloons able to rise up? This is because of the convection process. You may have seen the heater at the bottom of the balloon. This heater heats the air that lifts the balloon.
9. Hot Beverage
You can see steam coming out of a cup of hot coffee. Steam in the form of warm air rises due to the heat of the liquid. This steam is transferred to the air. This is also an example of the convection principle.
10. Rainfall and Thunders
One of the interesting examples of convection on earth is rainfall and thunder. Clouds form when seawater heats up and rises. These warm water droplets, in turn, saturate which leads to the formation of clouds. Then, the small clouds collided with each other and developed bigger clouds. Commonly called cumulonimbus, these large clouds cause rain and thunderstorms.

FAQ
What Are Convection Currents 3 Examples?
Examples of convection currents are all around us. Convection currents are what cause sea breezes. Air warmed over the land rises, and cooler air from over the ocean rushes in to replace it. Just as warmed air is less dense than cooler air, a hot soup in a cup is less dense than before it was warmed.
What Is The Best Example Of Convection?
Convection currents are present in the air– A good example of convection current is the warm air that rises towards the ceiling in your house. The process happens as the warm air is said to be less dense than that of the colder air. Another good example of convection current is wind.
What Is Convection In Daily Life?
Everyday Examples of Convection. Boiling water – The heat passes from the burner into the pot, heating the water at the bottom. Then, this hot water rises and cooler water moves down to replace it, causing a circular motion. Radiator – Puts warm air out at the top and draws in cooler air at the bottom.
What Is Convection Examples For Kids?
Moving air with a fan or circulating water with a pump are examples of forced convection.
Conclusion
After reading this article, you know what are some examples of convection in detail. There are three processes of heat energy transfer and these are conduction, convection, and radiation. But the examples of conduction convection and radiation are different as these processes are also different. The molecular motion in fluids is the cause of convective heat transfer. So, you can confirm it by just observing the heating materialand learned about examples of convection.
