Heat flow takes place whever two objects  of differnet temperatures are brought into contact.  then if two objects have different temperes, heat will flow from the warmer object to the colder one.  in fluids particles can move easily from one place to another.  as the particles move, their energy goes along with them.  the closer together the particles in a substance are, the more effectively  they can conduct heat.  conduction works well in some solids, such as metals  but not as well in liquids and gases.  air and water do not conduct heat very well.  you were feeling energy coming directly from the sun as radiation.  recallt hat radiation is the direct transfer of energy electromagnetic waves.thermal energy the total energy or all or the atoms that make up an odject
