All three of these heat transfer methods are used to destroy your mouth when you bite into a Hot Pocket.

Convection really isn't heat itself moving but heated matter moving due heat.

TL;DR: Shaky things shake neighbouring things, shaky things rise above less shaky things, shaky things emit EM radiation that shakes things.
Note: These shakes are on the tiny tiny level, not the big big level. Vibration is big big, hotness is tiny tiny.
LankyFrog
now explain the differences on particle level
Particles wiggle. Some wiggle fast. Those ones are warm.

You'd know this if you'd studied, Joe

My professor scolded us when we used heat as a noun. "You can't have a bucket of heat" he would say. "to heat" is a verb / process.
GodelEscherBach
Your professor was an idiot. Heat is a quantity of energy being transferred between two bodies.
I had a teacher who insisted the centrifugal force didn't exist. I showed him the proof, and he didn't understand it.

Radiation transfers though curly bacon? Good to know!

CFA manual?
Nah just Google. Is CFA manual like a firefighter textbook? Here that's called IFSTA essentials and it covers this topic quite thoroughly.

Please explain to me why radiation isn't the same as convection?
Heated matter moving vs energy moving
Ah ok! So radiation is energy and convection is matter!

Isn't convection just conduction with an added step of heating the air?
ICanHasJava
Conduction is direct heating of a material (poker should be in fire) while convection is warm air.

Sounds like slavery with extra steps

Conduction is the heat that spreads itself. Convection is the movement of something hot.
stupendiferous
Movement of the fluid plays a big part In it
leadenjerry
Heat to neighbouring particles and thus the heat travels 2/2
In convection the heated particle itself travels and thus takes the heat with itself. In conduction the heated particle transfers its 1/2
SexualViolence
Sort of, but it can have different effects in the end (flash over by convection or a new ignition by conduction)
SaucyFineBolognaFactory
I think when the conductive material is a fluid that can expand and then take the heat away it's convection.
uzerok
Similar, but different. In convection particles are moving, in conduction particles (lattices) are vibrating with no notable net movement.
redmen79
Also, solids that conduct have a fluctuating surface temp, as the heat conducts away quickly.
Solids that heat by convection, like most plastics, have a more stable surface temp.
In the case of metals you also get free electrons that can vibrate even more, making solid metals good heat conductors.

Cereaza
Is that radiation? It kinda looks like "radiation" is just heat that goes sideways.
idenoh
or, put another way, radiation is matter releasing energy as heat.
Ninjainslippers
Yes, infrared radiation mostly. Heat is just excitement of particles, and any EM radiation causes that.
it is, heat is a form of radiation.
You're probably mistaken for ionizing radiation. Heat, light, sound, and any movement of electromagnetic energy can occur through radiation
That's what I understood radiation to be (EMR). I was just saying the image made it SEEM as though radiation was just heat moving sideways.
to be fair it does, it also goes in all other directions. I think using similar diagrams for convection and radiation isn't helping this

I'll show you anything you want, so long as you stop putting spaces before punctuation like that.
I sometimes add extra whitespace for better readability. Now, show the goods.

Uh... that was not about thermodynamics? +1 for the short attention span.
You said "Show me the goods." so I sent you greats.
