Another video for covid shut-ins. I'll do a few before the virus comes knocking at the door. The virus is a great example of what happens when the PR departments are in charge.
Okay that was good too. I hadn't thought of heat conduction- only capacity, so that was good to know/understand Convection- hotter less dense rises cooler more dense sinks? Is this the same as when you walk in the valley and it's cooler from the cool air rolling downwards- same idea right?

Yes, cold air sinks to the ground. It's the mechanism for frost.
