What are non-examples of conduction?
Non-examples of conduction include radiation and convection. Radiation is the transfer of heat through electromagnetic waves, such as sunlight warming the Earth. Convection is the transfer of heat through the movement of fluids, such as boiling water transferring heat through the rising bubbles. Conduction specifically refers to the transfer of heat through direct contact between objects or substances.
What is the method by which heat is transferred into in a fluid liquid or gas?
Transfer of heat in nature occurs through three ways: conduction, convection and radiation. Conduction takes place in solids. Convection in liquids and gases. Radiation takes place in all three media as well as in vaccum.
If a heater claims to be 1500 watts how long would it take for that heater to draw 1500 watts?
Watts is the amount of power the heater has and amps would be the draw- if it is a 120 volt heater than the amps would be 12.5 amps and it is instantaneous
Difference between convection and conduction?
Convection is a natural process that occurs in nature all the time, and even in your kitchen. Take a pot of boiling water for example. the water closer to the flame becomes hotter than the water near the top of the pot. As we all know, warm things rise, and cold things fall. So the hot water replaces the cooler water at the top of the pat. Where does the cold water go? It is forced to the bottom of the pot, where it too is then heated up, and replaces the water at the top of the pot that by now has cooled of. In simpler terms, convection is the circulation of LIQUID (or GAS), driven by heat (or cold). Conduction would have to do with WHAT the pot is made of, and how quickly/easily heat is transfered through it. Most of the time, conduction travels through SOLIDS (and sometimes GASES, i believe). Take a light bulb and a batterie, for example. To create a circuit, you need energy to get from the batterie, to the lightbulb, and then back again. If you were to use wires made off rubber, the electricity would not transfer through the wiring. You would have to use a wire made of some sort of conductive material. Hope this helped a bit!
Where will convection most likely occur?
Convection is the process of heat transfer through a liquid or gas, so it's like conduction except it is through a liquid or gas. An easy example is to think of a pot of stew after it is done cooking and is removed from the stove. Denser material like beef, potatoes, vegetables, etc. will settle to the bottom of the pot. The broth remains on top and heat transfer occurs from the liquid first and faster than from the denser materials. The convection from the broth actually helps cool the denser material below.
Does grilled meat use conduction convection or radiation?
cooking grilled meat would use radiation some convection. conduction would cook the inside.
Would a mobile turning because a candle below it be an example of convection?
No, that would be an example of conduction, not convection. Convection involves the transfer of heat through the movement of fluids (liquids or gases), while conduction involves the transfer of heat through direct contact between materials.
If an entire lake is heated by water from a hot spring at the bottom of the lake what kind of heat transfer would that be?

Does cooking grilled meat use conduction convection or radiation?
Cooking grilled meat uses a combination of conduction, convection, and radiation. Conduction occurs when the meat comes in direct contact with the hot grill grates, transferring heat energy. Convection happens as hot air circulates around the meat, cooking it evenly. Radiation plays a role as the heat from the grill's flames or electric coils directly heats the meat's surface.
What is a example of a convection but not conduction?
An example of convection without conduction would be the boiling of water in a pot. As the water heats up at the bottom of the pot, the hotter water rises to the top and cooler water moves downward to replace it. This creates a convection current that circulates the water, heating it evenly throughout the pot.
What is the opposite from convection?
The opposite of convection would be conduction, which is the transfer of heat through direct contact between particles or objects. In conduction, heat is transferred through a material without any bulk movement of the material itself, unlike in convection where heat is transferred through the movement of fluids such as air or water.
What are non-examples of conduction?
Non-examples of conduction include radiation and convection. Radiation is the transfer of heat through electromagnetic waves, such as sunlight warming the Earth. Convection is the transfer of heat through the movement of fluids, such as boiling water transferring heat through the rising bubbles. Conduction specifically refers to the transfer of heat through direct contact between objects or substances.
Does an oven have conduction or convection?
Pizza in an oven recieves heat by radiation from the hot metal casing, and the burner, and by conduction from the air. Convection only heats fluids; so the air around the pizza (which is cooled by it) flows in convection currents, and interracts with hotter air. The pizza is heated faster because of convection heating taking place, but is not heated by it direction.
How does the the process of convection rely on conduction?
The air directly above the Earth's surface is heated by conduction. Warm air is then circulated through the atmosphere by convection currents.
What the transfer of energy as heat through a material?
That would normally be conduction unless the material is fluid - in which case you would have a combination of conduction and convection. In some cases a material may be sufficiently transparent to permit some heat transfer via radiation.
Is hair dryer an example of conduction or convection?
A hair dryer is an example of convection. Convection refers to the transfer of heat through the movement of fluids or gases. In the case of a hair dryer, the heat is generated by an electric element and is then transferred to the surrounding air. The heated air is then blown out of the hair dryer and onto the hair, drying it by convection. Conduction, on the other hand, refers to the transfer of heat through direct contact between objects. An example of conduction would be touching a hot stove and feeling the heat transfer to your hand through direct contact. It is important to note that both convection and conduction can occur simultaneously in many heat transfer situations. For example, a hair dryer may also transfer heat to your hair through conduction as the hot air comes into contact with your hair.
Is using air circulations to cook food conduction?
No, it would be convection: because the energy is circulating, due to heat differential (convecting), through the air.
