why is it easier to heat things up, than it is to cool them down?
In: 143
Heat is by definition ceaseless random motion in the molecules of an object. If you add energy to the object, you get heat (or acceleration but we’re not talking about that).
Now energy is a thing. You can point to it and say hey look there is energy.
Lack of energy, in contrast does not exist. Cold is a lack of energy. You cannot pump cold into a thing.
Thus, if you have energy you can put it in an object. There’s nothing you can put into an object to make it colder so the process of cooling things is much more passive. You have to connect the object to something that will take the energy away.
It’s just a more complicated process.
