Natural Convection occurs when a warmer less dense fluid is pushed away by a cooler denser fluid. Forced Convection occurs when an outside force pushes a fluid, such as water of air, to make it move and transfer heat. A fan is a perfect example. Im pretty sure air, and heat vents are examples too. An air conditioner is definitely an example.

Convection always occurs in what two forms?
forced and natural convection possibly
What is difference between free and forced convection?
free convection : the transfer of heat resulting from differences in density of air, that thereby causes the flow of air. mechanical convection the transfer of heat resulting from a blower or fan that actively forces heated air throughout all areas
Convection only occurs in due to particles moving not just heat transfer as in conduction?
Yes, convection is the transfer of heat through bulk movement of a fluid, gas or liquid. The movement can be natural caused by density differences, or can be forced.
What does free and forced convection mean?
Forced convection is when air ascends as a result of another force, such as the actions of fronts, orographic lifting, or converging wind. Free convection is caused by a factor such as intense heating of the Earth's surface, which warms air and causes it to rise.
An example of forced convection is the movement of hot air by a fan?
True
What is the Difference in normal convection and forced convection?
Forced convection is forced [man-made] and normal convection is natural.
What is the difference between natural and forced vibrating systems?

What are the two types of air cooled condenser?
Air cooled condensers are of two types: natural convection and forced convection. In the natural convection type, the air flows over it in natural a way depending upon the temperature of the condenser coil. In the forced air type, a fan operated by a motor blows air over the condenser coil.
What is the difference between ventilation and gaseous exchange?
Gaseous exchange is a natural process, ventilation is a forced process.

What are two types of convection?
Convection is broadly the movement of any molecules through any fluid state, including liquids and gasses. It is the primary form of heat and mass transfer on Earth, and can be found in many systems around the world. Many people are familiar with convection from heating their food or their houses, and it also plays a pivotal role in creating the weather conditions on the planet. There are two main types of convection: forced convection and natural convection. Natural convection occurs when the medium transferring the heat is being inspired to move by the heat itself. This happens both because the medium expands as it heats up, as in the case of gases, and also because buoyancy causes the warmer fluid to rise. Natural convection is also sometimes referred to as free convection. The two types of convection, forced and natural, often occur at the same time, where the heat is causing the fluid to move somewhat, but it is also moving because of some other force. In this case, it is referred to as mixed convection. Forced convection can be seen in many places in the world, both in man-made objects and in the natural world. For example, a convection oven forces heated air to circulate through the oven by using a fan. Although the air might move somewhat on its own, the forced convection allows for an even disbursement of heat. Within the human body, the circulatory system is another great example of forced convection. Blood, among its many other uses, acts as both a heating agent and cooling agent for the body, and is forced through the circulatory system.
What is the difference between Forced vital capacity and vital capacity?
there is no difference.
What are the applications of forced convection?
Forced convection are used in car radiators, cooling towers, air cooled heat exchangers etc.
