Physics 24A Heat Conduction Examples (22 of 22) Temperature at Both Junctions?

We will find the heat loss/sec=? through the insulation of a 20cm insulated copper wire of variable heat flow.

First video in this series can be seen at:

Awesome... Heat transfer eq for conductivity Q = (T1- T2)/ (L/KA) or Q= -KA dt/dx.

Michel, You mentioned the hazards of insulating double-pane glass with a vacuum and I came across this in Goggle:
"Argon is the gas most often used between panes in a double- or triple-glazed window. It's colorless and odorless and is denser than the atmosphere, providing more thermal efficiency than having air"... [ or nothing]..." between the panes."

Temp. Unit of k in kelvin or centigrade pls?
