How does heat move from object to object?

Answer 1

heat moves from object to object in three major ways[conduction,convection and radiation].in conduction a material medium is required for the heat to be transferred and molecules transfer the heat,an example is when you put a spoon into a hot water,at first the handle of the spoon is not warm but before long it becomes warm showing you that heat has been transferred from the molecules of the hot water to the whole spoon through the molecules of the metal making up the spoon,in convection heat is transferred through the circulation of the molecules of the substance majorly liquid or gas,an example is what happens when you boil water,the heat energy given out from the fire moves through the water molecules in a cyclic manner,in radiation a material medium is not required instead the heat is transferred directly from the source to the receiving medium,an example of this is the process which the heat of the sun reaches us on earth.
when two objects are touch with each other and they are in different temperatures,thermal energy is flowing of the object witch is in high tempreture to the object witch is in low temperature.and that because of the difference of temperatures between these two objects.they flow heat in order to become balanced(this level is called thermal equilibrium.)
but you must pay attention that when we call this energy "thermal energy" that it is flowing.when this energy delivers to another object,we don't call it thermal energy, it is called "internal energy". so thermal energy is only the energy witch is in the way to deliver to the other object!
