Un trozo de 5 kg de hierro se encuentra con una temperatura inicial de 300° C. Calcula su temperatura final si se sabe que pierde 5 kcal de calor.​

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
