1. A glass flask whose volume is 1000.00 cm3 at 0.0'0 C is completely filled with mercury at this temperature. When flask and mercury are warmed to 55.00 C, 8.95 cm3 of mercury overflow. If the coefficient of volume expansion of mercury is 18.0 x 10'5 K4, compute the coefficient of volume expansion of the glass. An electric kitchen range has a total wall area of 1.40 m2 and is insulated with a layer of fiberglass 4.00 cm thick. The inside surface of the fiberglass has a temperature of 175CJr and its outside surface is at 350C. The fiberglass has a thermal conductivity of 0.040 W/m - |(. What is the heat current through the insulation, assuming it may be treated as a flat slab with an area of 1.40 m2? 2. Suppose that the rod is made of copper, is 45.0 cm long, and has a cross-sectional area of 1.25 cm2. Let T. = 100.0C and Tc = 0.0\"C. What is the final steady-state temperature at a point in the rod 12.0 cm from its 'Ieft end
