Respuesta :
They must have different temperatures.
Heat is only transferred if two objects have a different temperature, which also means that their particles move at different speed and have different kinetic energy. In addition, heat must be transferred from the hotter object to the cooler one.
Usually in metals, since they have a large number of free electrons, heat can be transferred when the free electrons move and collide with other particles and pass the energy on and on. The faster they move, the faster heat is transferred. Metals can be very efficient in transferring heat compared to other materials where there are less free electrons as free electrons can travel a long distance before colliding with other particles.
So next time if you try and touch a metal spoon, you feel coldness because heat is transferred from your hand to the spoon as they have different temperatures.

If there is a net flow of heat between the blocks, they must have different temperatures.
What is temperature?
Temperature is the measure of hotness or coldness expressed in terms of any of several scales, including Fahrenheit and Celsius.
Heat will flow from the high temperature region to the low temperature region until the temperature distribution is the same throughtout the body. Or, there may be a temperature gradient across an object. Heat will flow so as to equalize the temperature throughout the object.

The faster they move, the faster heat is transferred. Metals can be very efficient in transferring heat compared to other materials where there are fewer free electrons as free electrons can travel a long distance before colliding with other particles.
