Radiation is when heat is transferred from one thing to another via electromagnetic waves like infrared. It can travel through a vacuum. Convection is when a fluid is heated from the bottom and rises, leaving colder fluid behind to be heated etc creating currents. The thing you are trying to heat has to be in contact with the heat source- it doesn't work through a vacuum.
What else can I help you with?
What is the difference between physics and rad physics?
Rad Physics is physics applied to radiation
Why does the energy from the sun travel to earth by radiation instead of by covection or conduction?
The sun moves through the electromagnetic waves. Conduction and Convection transfers energy between differences in density.
What 4 ways transfer of heat energy?
conduction convection radiation direct contact
Is warming ocean water through water currents radiation?
No. Heat transfer through a liquid or gas by currents is convection.
Heat given off by a fire in a fireplace is an example of - A conduction B Convection C radiation D insolation?
Radiation. Conduction is when one object takes heat from an object adjacent to it, like your hand on a hot plate. Convection is when heat travels through a gas or a liquid to get from one place to another, like a hair dryer to your hair. And Radiation is when heat travels through rays like the sun or a flame. Based on technicalities regarding the question, the flame can heat the surrounding air and travel to you, thus being a convection current.
What is one key difference between radiation and convection zones?
One key difference is that in a radiation zone, energy is primarily transferred through electromagnetic radiation, while in a convection zone, energy is transferred through the movement of hot gas or liquid. Radiation zones are generally more stable and characterized by slow energy transfer, while convection zones are more dynamic and turbulent.
How is transfer of energy by radiation differ from either conduction or convection?
Transfer of energy by radiation does not require a medium and can occur through a vacuum, unlike conduction and convection which require a material medium. Radiation involves the movement of electromagnetic waves, such as infrared radiation, while conduction and convection involve the transfer of heat through direct contact or movement of a fluid, respectively. Radiation is not dependent on the temperature difference between objects, unlike conduction and convection which rely on temperature differentials for heat transfer.
How do you explain the difference between conduction convection or radiation can transfer heat explain?
It's a different way to transfer heat. One object emits electromagnetic radiation (for example, infrared - though it depends on the temperature); another object absorbs it. Heat transfer through radiation can occur in empty space; with conduction and convection, that's not possible.
What are the methods of heat transfer?
convection, conduction and radiation
What are 3 methods of heat transfer?
Heat (or thermal) energy is kinetic energy due to motion of atoms and molecules. It is energy that is in the process of being transferred from one object to another because of their temperature difference
What is the difference between the convection and convection bake settings on your oven?
convection warms and convention bake bakes
What is the difference between a convection oven and a convection microwave oven?
A convection oven moves the air, a microwave does not.
Is a oven a radiation conduction convection?
is a oven a radiation convection or conductin
What is the thermal energy that is transferred?
Thermal energy that is transferred is known as heat. It can move from one object to another due to a difference in temperature between the two objects. This transfer of heat can occur through conduction, convection, or radiation.
How is heat transfer by radiation different from both convection and conduction?
Heat transfer by radiation does not require a medium for transfer, as it can occur through electromagnetic waves. In contrast, convection involves the transfer of heat through the movement of fluids or gases, while conduction occurs through direct contact between materials. Radiation can occur in a vacuum, while convection and conduction require a medium.
Is there a difference between convection cooking and convection baking?
direct and indirect passage of fuel
How was radiation fundamentally different from conduction and convection how is radiation fundamentally different from conduction and convection?
Radiation differs from conduction and convection in that it does not require a medium to transfer thermal energy. Conduction transfers heat through direct contact between materials, while convection involves transferring heat through the movement of a fluid. Radiation can occur in a vacuum and does not rely on the movement of particles.
