OverviewWhat is thermal conduction?What's the equation for the rate of thermal conduction?What does each term represent in the thermal conduction equation?Why do metals feel both colder in the winter, and hotter in the summer?Example 1: Window makeoverExample 2: Window heat lossThere's a lot to digest in the equation for thermal conduction Qt=kAΔTd . Let's look at what eac…Qt : The factor on the left hand side of the equation (Qt) represents the number of joules of heat energy transferred through the material per second . This means the quantity Qt has units of joulessecond=watts .k : The factor k is called the thermal conductivity constant. The thermal conductivity constant k i…[How can k change if it is a constant?]See more on khanacademy.org There's a lot to digest in the equation for thermal conduction Qt=kAΔTd .
