Convection - hot air raises -- smoke and other hot air goes up.
Conduction - anything in contact with the fire - a pot, a Poker, etc conducts the heat
Radiation - some of the energy ( heat) is released as infrared (heat) waves
you can feel the heat without touching the fire thru radiation of these i-r waves.

Is radiation the transfer of heat by the movement of a fluid?
No, most forms of radiation have nothing to do with heat. Transfer of heat by the movement of a fluid is called convection.
What similarity have convection and radiation?
Both are forms of heat transfer.
A fire warms you by transferring what energy?
There's only one kind of heat energy. I'm guessing that you meant heat transfer. A person sitting in front of a fireplace feels two of the three kinds of heat transfer. Conduction, the first, is minimal, because there is little or no contact between the fire and the person: conduction is only through contact. Convection, the second type, is heat transfer through fluids: i.e. liquids and gases. Presumably, no liquid is involved, but the fire heats air, which heats up the person in turn. The third kind of heat is radiation, and it means heat transfer through electromagnetic waves. The fire does produce electromagnetic waves (infrared and visible, at the very least), because the chemical energy of the wood is being released. The energy that strikes the person is then absorbed, and the person feels heat.
Is the heat transfer from a barbecue fire to a person standing in front of it a good example of heat transfer by conduction?
No. Not unless the person touches the BBQ. More a case of heat radiation.
Which forms of heat transfer are described helping to create a sea breeze?
convection and conduction

A toy boat is floating in a large metal bucket If you build a fire under the bucket how the heat will transfer from the fire to the boat?
Water molecules will transfer heat as they move from the lower part of the bucket to the boat.

No. Not unless the person touches the BBQ. More a case of heat radiation.
What form of heat transfer helps create a sea breeze?
Two forms of heat transfer help create a sea breeze are conduction and convection. Another form of heat transfer help create a sea breeze is radiation.
What kind of heat transfer is used for shallow frying?
use gas and fire.
What 2 forms of heat transfer contribute to the creation of a land breeze?
Convection & Conduction
Which forms of heat transfer are described helping to create a sea breeze?
convection and conduction
Which two forms of heat transfer or work together to heat water in a plastic bottle?
convention and conduction
Why does heat reaching your body through camp fire is only by radiation and not by conduction and convection?
Normally, people sit beside a fire. The heat reaching our body cannot be heat transfer by convection since this transfers heat vertically due to density changes. Horizontally, heat cannot be transferred by convection. Air is such a poor conductor that it is impossible that the heat transfer is made by conduction. By elimination, we can conclude that the heat transfer in this case is by radiation.
