Multiple Choice

Some properties of a certain glass are listed here:
Density $2300 \mathrm {~kg} / \mathrm { m } ^ { 3 }$
Specific heat capacity $\quad 840 \mathrm {~J} / \mathrm { kg } \cdot \mathrm { C } ^ { \circ }$
Coefficient of thermal expansion $8.5 \times 10 ^ { - 6 } \left( \mathrm { C } ^ { \circ } \right) ^ { - 1 }$
Thermal conductivity $\quad 0.80 \mathrm {~W} / \mathrm { m } \cdot \mathrm { C } ^ { \circ }$
A glass window pane is 2.7 m high, 2.4 m wide, and 9.0 mm thick. The temperature at the inner surface of the glass is $19 ^ { \circ } \mathrm { C }$ and at the outer surface $4 ^ { \circ } \mathrm { C }$ How much heat is lost each hour through the window?

• A) \(3.1 \times 10 ^ { 7 } \mathrm {~J}\)
• B) \(3.1 \times 10 ^ { 5 } \mathrm {~J}\)
• C) \(8.6 \times 10 ^ { 3 } \mathrm {~J}\)
• D) \(3.1 \times 10 ^ { 4 } \mathrm {~J}\)
• E) 8.6 J
