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 is the difference between physics and rad physics?
Rad Physics is physics applied to radiation
What 4 ways transfer of heat energy?
conduction convection radiation direct contact
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.
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 the difference between conduction convection and thermal energy?
Conduction and convection are two ways in which thermal energy is transferred, the third way is by radiation.
What are the methods of heat transfer?
convection, conduction and radiation
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 is an energy transfer due to a difference in temperature?
conduction, convection or radiation
What is an energy transfer due to difference in temperature?
conduction, convection or radiation
What are the three forms 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
Is a oven a radiation conduction convection?
is a oven a radiation convection or conductin
What is a toaster convection or radiation?
convection
Is a oven a conduction convection or radiation?
is a oven a radiation convection or conductin
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.
