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.
Does heat always flow from cooler objects to warmer?
Heat always flows from warmer objects to cooler objects, unless you have a device (like a heat pump) to prevent this. The natural tendency is for two or more objects at different temperatures to eventually all have the same temperature and this is accomplished by heat flowing from the warmer objects to the cooler objects.
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.
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
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.
When two objects are touching and transfer heat is called?
Conduction

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.
