Question 1

Some properties of a certain glass are listed here:

Density2300 kg/m3
Specific heat capacity840 J/kg ∙ °C
Coefficient of thermal expansion8.5 × 10-6 (°C)-1
Thermal conductivity0.80 W/m ∙ °C

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 and at the outer surface 4°C. How much heat is lost each hour through the window?
◦ 8.6 J
◦ 8.6 × 103 J
◦ 3.1 × 107 J
◦ 3.1 × 104 J
◦ 3.1 × 105 J

Question 2

The figure shows a graph of the temperature of a pure substance as a function of time as heat is added to it at a constant rate in a closed container. If LF is the latent heat of fusion of this substance and LV is its latent heat of vaporization, what is the value of the ratio LV/LF?



◦ 1.5
◦ 4.5
◦ 3.5
◦ 5.0
◦ 7.2
