A dual-pane window in a house is composed of two parallel panes of glass, each with an area of 2.23 m². Each pane of glass is 3.10 mm thick and the space between the panes is 12.5 mm thick and is filled with argon. (a) Calculate the heat flow through the window if the indoor temperature is 18.3°C and the outdoor temperature is -20.6°C (this is about -5°F). (b) Determine the temperature on the inside of the pane (this is in the argon-dilled region) closest to the outside of the house.

Temperature Difference and Heat Transfer

Whenever there is a flow of heat flux resulting from a temperature gradient within the material or between two materials, there is heat transfer. Heat transfer primarily arises due to temperature differences between two bodies or within bodies. The term temperature gradient denotes temperature differences or variation of temperature due to change in some quantity. The fundamental use of the concept of temperature is found in the zeroth law of thermodynamics.

Question

A dual-pane window in a house is composed of two parallel panes of glass, each with an
area of 2.23 m². Each pane of glass is 3.10 mm thick and the space between the panes
is 12.5 mm thick and is filled with argon.
(a) Calculate the heat flow through the window if the indoor temperature is 18.3°C and
the outdoor temperature is -20.6°C (this is about -5°F).
(b) Determine the temperature on the inside of the pane (this is in the argon-dilled
region) closest to the outside of the house.
