What are 3 ways heat is produced?
Conduction, convection and radiation TRANSFER heat; you can't create heat; the law of conservation of energy states that energy cannot be created or destroyed. Therefore, you can't create heat.
How do convection conduction and radiation differ?
Those are three different means by which heat can travel. In convection, heat is carried by moving matter. In conduction, heat is transferred by means of a physical contact between two objects of different temperature. With radiation, energy is emitted in the form of electromagnetic radiation, usually in the infrared spectrum.
What are the types of heat flow and how do they differ?
Conduction (The transfer of heat from one substance to another by direct contact.) Convection (A technical way of saying that heat rises and this sets up air currents.) Radiation (Radiation describes any process in which energy travels through a medium or through space, ultimately to be absorbed by another body.)
How does the transfer of energy in the radiative zone differ from the transfer of energy in the convective zone?
In the radiative zone, energy moves from atom to atom in the form of electromagnetic waves, or radiation. Energy produced in the core moves through this zone by convection, the transfer of energy by moving liquids or gases.
How does heat transfer?
Heat transfer occurs because in nature things are driven towards a point of equilibrium (all things being the same). This is expressed in the second law of thermodynamics which is an expression of the tendency that over time, differences in temperature, pressure, and chemical potential equilibrate in an isolated physical system.Heat transfer happens in one of three ways.1 --- Conduction (direct transfer of heat by one object in contact with another)2 --- Convection (heat moving by means of air)3 --- Radiation (light energy).

What is the differ of conduction and convection?
conduction by itself is slower to heat but conduction and convection is faster to heat
The transfer of heat by means of rays?
Radiation is the means of heat conduction through electromagnetic (EM) waves. These waves are known as Thermal radiation and differ from other EM waves as Radio waves, Microwaves etc. The other two methods of heat transfer are Conduction and Convection where both require a medium (such as air, water etc.) for the transfer to take place.
How do convection conduction and radiation differ?
Those are three different means by which heat can travel. In convection, heat is carried by moving matter. In conduction, heat is transferred by means of a physical contact between two objects of different temperature. With radiation, energy is emitted in the form of electromagnetic radiation, usually in the infrared spectrum.
How does convection and conduction differ?
I don't know. Radiation stimulates atoms whereas conducton and convection increase the volume. This answer is correct because my science teacher checked it and I did a project on it. thanks

How convection and radiation are differ?
Both convection and conduction heat transfer need a medium (for example air particles, water, metal) through which to travel along with a temperature gradient within the medium. Radiation heat transfer does not need a medium through which to travel, it actually occurs most effectively in a perfect vacuum environment. Radiation is not just the heat from the sun, although the sun does in fact radiate heat. Everything around you is currently radiating heat as well (for example humans, computers, furniture, books, food, etc.)

How does convection differ from convection?
Well it differs in this way. Conduction is when heat is applied to an object and causes mainly the point of contact to be heated. For example lighting a match under a metal rod. It will mainly heat the point of contact, eventually heating the rest of the rod. Additionally, conduction can be referred to when talking about electricity and whether a material can conduct or not. Convection is different as it disperses heat evenly through a liquid. For example, boiling water. A single point of the water is heated, then it rises, allowing colder water from the top to fall, heat, rise and creates a current, evenly heating the water. The same example can be used when referring to preheating an oven. Hopefully this helps. Convection involves the actual movement of fluid materiel, either liquid or gas, usually in a gravitational field where the difference in temperature causes difference in density which in turn causes fluid motion. Conduction can and does occur concurrently with convection, but does not involve the macroscopic movement of materiel. Conduction can occur in gasses or liquids, but also in solids. Conduction occurs when the thermal vibrations of hotter mater are transferred to cooler matter. There is a third method of heat transfer, Radiation. Radiation can occur in all three phases of matter, but can also transfer heat across a vacuum. Usually thermal radiation is in electromagnetic wavelengths too long to be visible, but in some situations like an incandescent bulb or the sun, it can be seen.
