    A glass window 0.60 cm thick measures 83 cm by 42 cm. How much heat flows through this window per minute if the inside and outside temperatures differ by 18°C?
    _______ kJ/min

    The conversions are confusing me.

    The solution is attached below in two files. the files are identical in content, only differ in format. The first is in MS Word format, while the other is in Adobe pdf format. Therefore you can choose the format that is most suitable to you.

    The heat flow rate in Watts is given by:
    (1.1)
    Where k is the glass' thermal conductivity coefficient, A is the cross section area, x is the thickness of the glass and T is the temperature difference between the two sides.

    In our case (recall that a difference in one degree Celsius is equivalent to a difference of one degree Kelvin):
