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

I just took a semester class on this topic. I hated it.

Mr Flanders and Swann has an awesome video on said topic. https://youtu.be/VnbiVw_1FNs?t=126

TL;DR: Shaky things shake neighbouring things, shaky things rise above less shaky things, shaky things emit EM radiation that shakes things.

8 years ago | Likes 3 Dislikes 0

Note: These shakes are on the tiny tiny level, not the big big level. Vibration is big big, hotness is tiny tiny.

8 years ago | Likes 2 Dislikes 0

now explain the differences on particle level

8 years ago | Likes 1 Dislikes 0

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.

8 years ago | Likes 2 Dislikes 0

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.

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?

8 years ago | Likes 1 Dislikes 0

Heated matter moving vs energy moving

8 years ago | Likes 2 Dislikes 0

Ah ok! So radiation is energy and convection is matter!

Isn't convection just conduction with an added step of heating the air?

8 years ago | Likes 42 Dislikes 0

Conduction is direct heating of a material (poker should be in fire) while convection is warm air.

8 years ago | Likes 2 Dislikes 3

Sounds like slavery with extra steps

8 years ago | Likes 6 Dislikes 2

Conduction is the heat that spreads itself. Convection is the movement of something hot.

8 years ago | Likes 5 Dislikes 0

Movement of the fluid plays a big part In it

8 years ago | Likes 42 Dislikes 0

Heat to neighbouring particles and thus the heat travels 2/2

8 years ago | Likes 1 Dislikes 0

In convection the heated particle itself travels and thus takes the heat with itself. In conduction the heated particle transfers its 1/2

8 years ago | Likes 1 Dislikes 0

Sort of, but it can have different effects in the end (flash over by convection or a new ignition by conduction)

8 years ago | Likes 1 Dislikes 0

I think when the conductive material is a fluid that can expand and then take the heat away it's convection.

8 years ago | Likes 2 Dislikes 1

Similar, but different. In convection particles are moving, in conduction particles (lattices) are vibrating with no notable net movement.

Also, solids that conduct have a fluctuating surface temp, as the heat conducts away quickly.

8 years ago | Likes 2 Dislikes 0

Solids that heat by convection, like most plastics, have a more stable surface temp.

8 years ago | Likes 1 Dislikes 0

In the case of metals you also get free electrons that can vibrate even more, making solid metals good heat conductors.

Is that radiation? It kinda looks like "radiation" is just heat that goes sideways.

8 years ago | Likes 6 Dislikes 0

or, put another way, radiation is matter releasing energy as heat.

8 years ago | Likes 1 Dislikes 0

Yes, infrared radiation mostly. Heat is just excitement of particles, and any EM radiation causes that.

8 years ago | Likes 7 Dislikes 0

it is, heat is a form of radiation.

8 years ago | Likes 9 Dislikes 0

You're probably mistaken for ionizing radiation. Heat, light, sound, and any movement of electromagnetic energy can occur through radiation

8 years ago | Likes 4 Dislikes 1

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.

8 years ago | Likes 2 Dislikes 0

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.
