What is the transfer of energy by the movement of fluids or gases with different temperatures?
Convection
What is the transfer of energy as heat caused by the collision of molecules?
When molecules collide and there is a transfer of energy as heat, this is called conduction. When fluids of different temperatures transfer energy by movement, this is called convection.
How long does thermal energy transfer between objects?
Since different objects have different heat conductivity and different temperatures and heat capacities, the time can vary without limit.
What term describes the transfer of energy between objects that have different average kinetic energies?
The transfer of energy between two objects at different average thermal kinetic energies (temperatures) is referred to as heat transfer. It is always called heat transfer, regardless of what kind of energy is being transferred.
What informtion do you need in order to predict whether heat transfer would occur when two objects or materials interact?
All you need is their temperatures. If their temperatures are different, then heat will flow from the warmer one to the cooler one.

What is the transfer of thermal energy between two bodies which are at different temperatures?
Thermal energy can be transferred by conduction, convection, or radiation. The formulae for the rate of transfer - if that's what you are after - vary, depending on which type of transfer is predominant.

Which method of heat transfer can take place if two objects at different temperatures are place if two objects at different tempertaures are placedwithout touching each other in a vacuum?
Radiation.

All you need is their temperatures. If their temperatures are different, then heat will flow from the warmer one to the cooler one.
Is there any heat exchange between object and the surrounding atmosphere?
As long as the body and the surrounding atmosphere are at different temperatures, there will be heat transfer between the two.
What causes the transfer of energy from object to another?
Differences in temperatures.
Which method of heat transfer can take place if two objects at different temperatures are placed without touching each other in a vaccum placed?
radiation, i think
Why does energy transfer from one molecule to the other when the two are at different temperatures?
The temperature of a molecule/particle is a mesure of its energy, the more energy it has, the faster it will move and the higher its temperature will be; if you have two molecules at different temperatures they will therefore be moving at different speeds, and so if and when they collide, the faster/hotter one transfers energy to the slower/colder one. (This same basic principal applies in many situations, in a collision between two cars/people for example, they will usually go in the same direction as the person with the most momentum.)
