Some double-glazing system trap air between two panes of glass. A.) explain how energy is transferred through a double-glazed window from a hot room to the cold air outside.
B.) state and explain how the rate of energy transfer would change if you removed the air from the gap.

Athin, square metal plate measures 14 cm on each side and has emissivity of 0.60. the plate is heated to a temperature of 745°c. what is the rate at which the plate radiates energy ? the stefan-boltzmann constant is 5.67 × 10-8 w/(m2 ? k4). remember that the plate will radiate energy from both its top and bottom surfaces.
