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.
A line was measured to be 412 m using a 30-m tape, which is of standard length at a temperature of 20 deg.C. During measurement, the temperature was 52 deg.C. If the coefficient of thermal expansion of the tape material is 0.0000116 m/m deg.C, calculate the correct length of the line.

tension of mercury at 20°C in contact with
air is 0.57 N/m respectively. The angle of
contact for mercury is 130⁰.
