When they are in thermal contact and their temperatures are the same there is no NET flow of energy. If the objects are both thermally insulated there will be no flow of energy at all.
Heat is the transfer of energy from one substance to another. So when you get cold, you are getting cold from the heat. Your body is giving energy to the air around you. So heat is the answer
This is heating and cooling. Direct transfer from one solid to another is conduction. Transferring through fluids (liquids or gases) normally uses convection. and heat being projected through a...
