A window panel that measures 20.0 cm by 15.0 cm is set into the front door of a house. The glass is 0.32 cm thick. The temperature outdoors is −15°C and inside is 22°C. (C glass=0.63 W/mk) a)calculate the heat transfer for a single window. (house) b) calculate the heat transfer for the double-gated window. c)calculate the heat transfer for the Tripple gated window. d)calculate the heat transfer for the quadruple glazed window.
Energy transfer
The flow of energy from one region to another region is referred to as energy transfer. Since energy is quantitative; it must be transferred to a body or a material to work or to heat the system.
Molar Specific Heat
Heat capacity is the amount of heat energy absorbed or released by a chemical substance per the change in temperature of that substance. The change in heat is also called enthalpy. The SI unit of heat capacity is Joules per Kelvin, which is (J K-1)
Thermal Properties of Matter
Thermal energy is described as one of the form of heat energy which flows from one body of higher temperature to the other with the lower temperature when these two bodies are placed in contact to each other. Heat is described as the form of energy which is transferred between the two systems or in between the systems and their surrounding by the virtue of difference in temperature. Calorimetry is that branch of science which helps in measuring the changes which are taking place in the heat energy of a given body.

Also:
1.find out what is used in those gaps (not air or vacuum or left empty)
2. find out the standard gap dimensions
3.what is the specific heat capacity of the substance that is used in those gaps
4.calculate and compare the heat transfers
