Hot and Cold, Pt. 2

I feel like it's way easier to make things hot than cold. For instance, if I were to hand you a room-temperature object, you could raise it's temperature by 10 degrees much easier than you could cool it by 10 degrees. Friction would be probably be the most simple way to raise an object's temperature, and I guess there are other (non-manmade) ways of raising an objects temp.

The only way I can think to lower an object's temperature is to get it wet and then blow on it to make the water evaporate. But that's so hard.

Help me, America.
