Which method of heat transfer can take place if two objects at different temperatures are placed without touching each other in a vacuum?

Heat doesn't travel through a vacuum. The energy could be changed to light and radiate across the gap, so that would be radiation.

What is the transfer of heat when to objects are not touching?
convection and radiation heat transfer bot occur without either object being in direct contact with each other.
When radiation occurs between two objects do the two objects need to be touching.?
The answer to this question is no. Radiation can occur when objects are not touching
What is a waffle iron type of heat transfer?
It is conduction, heat transfer where 2 objects touch, because the waffle iron and the waffle are touching. (and it can't be radiation or convection.)
Is heat transferred from a microwave to the food is a example of conduction?
No. It is an example of radiation. The heat is transferred by microwaves, which are a form of electromagnetic radiation. Conduction occurs when two objects of different temperatures are in contact or when different parts of an object have different temperatures.
The transfer of heat between two objects touching is called?
When a cold object and a hot object are in direct contact (touching) heat will be transferred through thermal conduction. Normally, heat transfer processes are categorized as thermal conduction, radiative transfer or convection. Heat transfer through thermal conduction is the direct transfer of kinetic energy from one molecule to the nearby molecules. Because temperature is directly proportional to kinetic energy, interactions between neighboring particles exchange energy and that exchange energy gradually works it way from the higher temperature regions to the lower temperature regions. The process of the temperature becoming the same is called thermal equilibration. Convective heat transfer occurs in fluids. If a gas, liquid, or other fluid, changes in fluid density change the buoyancy and will cause fluid to flow (a process called convection) and the heat contained in the warmer fluid is transferred to a new location by the physical movement of the fluid. Radiative transfer occurs when a hot object radiates electromagnetic energy. While the sun is an obvious source of electromagnetic energy, it is also generated in smaller amounts by any object. The hotter objects radiate more electromagnetic energy and the cooler objects absorb it. This radiative transfer is important but not as noticeable usually as the other two. It does occur between objects whether they are in direct contact or not, but is usually so small as not to be important of the objects are touching.
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.

radiation, i think
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.
How thermal energy travel?
Thermal energy travels by conduction, convection, and radiation. Conduction occurs when two or more objects of different temperatures are touching each other. The heat flows from the warmer object to the cooler object, until the objects reach equal temperatures. Convection is the transfer of thermal energy through a moving liquid or gas. Radiation is the transfer of thermal energy though matter and space.
How long does heat flow?
Until the objects touching have equal temperatures.

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.
