No es posible hacer algo más frío añadiéndole "frialdad".
Una sustancia solo puede enfriarse permitiendo que parte de su energía se transfiera a una sustancia de menor temperatura.
El calor es la cantidad de energía térmica transferida desde una región de mayor temperatura a una región de menor temperatura.
It is not possible to make something colder by adding "coldness" to it.
A substance can only be cooled by allowing some of its energy to be transferred to a substance of lower temperature
Heat is the amount of thermal energy transferred from a region of higher temperature to a region of lower temperature
