Describe how Dewar flasks limit energy transfer
A Dewar flask (thermos) is a device that resists energy transfer. Explain how Dewar flasks limit energy transfer by listing the equations for heat generated by conduction and heat generated by radiation and indicating which variables are minimized/maximized in order for heat transfer to be limited. Also address how Dewar flasks limit heat transfer via convection. Thanks in advance!
