Web6 de feb. de 2024 · From a hot object to a cold object. Ill give an example as to why: Say you place an ice cube in a glass of warm water, we know that in colder substances, the average kinetic energy per particle (which is the classical definition for temperature is lower). In hotter substances the average kinetic energy per particle is larger, as it is hotter. WebThe first statement of the 2nd law of thermodynamics - heat flows spontaneously from a hot to a cold body - tells us that an ice cube must melt on a hot day, rather than becoming colder. An explanation for this form … switch cleanerWebWhen a hot object is brought into contact with a cold object it is observed that the hot object cools down and the cold object warms up.
