The process of heating / cooling of an object in vacuum can be studied by the known Stefan's law. Many studies have investigated this phenomenon without inquire the role of the environment and of its temperature. In this paper the author proposes an experimental method through which to study the above process, by monitoring the ambient temperature on the assumption that this can vary with an exponential law. Under this hypothesis, in defined conditions, the temporal evolution of cooling of the object is similar to the case where the con- vection and / or the conduction are the principale phenomenon of energy exchange.
