What is an example of natural convection?
The driving force for natural convection is gravity.
For example if there is a layer of cold dense air on top of hotter less dense air, gravity pulls more strongly on the denser layer on top, so it falls while the hotter less dense air rises to take its place.
This creates circulating flow: convection..
What is an example of convection while cooking?
Examples of Convection Cooking Water coming to a boil and circulating in the pot. Running cold water over frozen food, which transfers heat into the food to thaw it more quickly. Room temperature air moving around frozen food to thaw it.
How do you use convection in a sentence?
Convection sentence examplesGerdien’s estimate of the convection current is for fine weather conditions. … The nearly vertical vanes is balanced by the convection currents. … This will be composed of a conduction and a convection current, the latter due to rising or falling air currents carrying ions.More items…
What is a fact about convection?
Convection is the movement of heat because of the movement of warm matter. For example, atmospheric circulation moves warm air to cool places, causing wind. … The movement of the clouds, the ocean currents and many types of heaters are examples of convection.
What is meant by convection current?
A convection current is a process that involves the movement of energy from one place to another. It is also called to as convection heat transfer. … These things happen as a result of the Convection Currents. The convection currents tend to move a fluid or gas particles from one place to another.
What is convection in simple words?
Convection is the circular motion that happens when warmer air or liquid — which has faster moving molecules, making it less dense — rises, while the cooler air or liquid drops down. Convection is a major factor in weather. … That current can result in wind, clouds, or other weather.
Are ovens convection?
A conventional oven has two heating elements that heat air inside the oven to cook food. … Since a conventional oven doesn’t have a convection fan to circulate hot air, pockets of hotter or cooler air can cause dishes to cook faster or slower, depending on their placement inside the oven.
What is a real life example of conduction?
A radiator is a good example of conduction. Anything placed on the radiator, like an article of clothing, will become warm. You can warm your back muscles with a heating pad. Roasting wieners over a campfire is fun until the heat from the fire is conducted up the coat hanger to your hand.
What are 2 examples of conduction?
What are 4 examples of conduction?Conduction: Touching a stove and being burned. Ice cooling down your hand.Convection: Hot air rising, cooling, and falling (convection currents)Radiation: Heat from the sun warming your face.
What is a good example of convection?
Everyday Examples of Convection radiator – A radiator puts warm air out at the top and draws in cooler air at the bottom. steaming cup of hot tea – The steam you see when drinking a cup of hot tea indicates that heat is being transferred into the air. ice melting – Ice melts because heat moves to the ice from the air.

What happens during convection?
Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated. … The denser cold liquid or gas falls into the warm areas.
