Transfer of heat by movement of a fluid

Transfer of heat between two objects that are touching each other

Transfer of thermal energy between two objects that are NOT touching each other

Transfer of heat by electromagnetic waves through a vacuum

Conduction

Radiation

Convection

All of the above

Yes, because convection requires objects to be touching each other.

No, because convection requires movement of particles and solids allows particles to move.

No, because convection requires movement of particles.Particles are fixed in a solid and cannot move.

Yes, because convection can happen in a solid since particles can move freely in any substance.

Conduction requires objects to be in direct contact (touching) and radiation can transfer heat without touching.

Conduction requires a fluid to transfer heat and radiation can transfer heat without touching.

Conduction requires objects to NOT be in direct contact (touching) and radiation can transfer heat without touching.

There is NO difference in conduction and radiation since they both transfer heat the SAME way.
