Refrigeration can seem a bit like magic -- how does a little bit of refrigerant being pushed around in some metal tubes somehow chill a freezer down to 0 degrees F? Well, it's not magic -- it's just physics. But granted, it's an aspect of physics that we don't often interact with in our daily lives, and it can be a bit unintuitive at first.

It all has to do with how a material can absorb heat without actually getting hotter. How does this happen? That's what we explain in this excerpt from one of our many full-length technical webinar recordings. This particular one is from our 5-part series on refrigerator thermodynamics.
