9. mmh One end of a brass bar is maintained at 306 °C, while the other end is kept at a constant, but lower, temperature. The cross-sectional area of the bar is 2.6 X 10-4 m². Because of insulation, there is negligible heat loss through the sides of the bar. Heat flows through the bar, however, at the rate of 3.6 J/s. What is the temperature of the bar at a point 0.15 m from the hot end?

9. mmh One end of a brass bar is maintained at 306 °C, while the other end is
kept at a constant, but lower, temperature. The cross-sectional area of the bar
is 2.6 X 10-4 m². Because of insulation, there is negligible heat loss through
the sides of the bar. Heat flows through the bar, however, at the rate of 3.6 J/s.
What is the temperature of the bar at a point 0.15 m from the hot end?

1. A cylindrical aluminum rod is positioned between two enclosed volumes, each con- taining a moles of water. One of these volumes consists of steam and liquid water in thermal equilibrium, while the other contains water and ice in thermal equilibrium. The rod has a length of 24.0 cm, and a cross-sectional area of 14.0 cm². It conducts heat from the hotter volume (condensing steam) to the cooler one (melting ice) in steady-state. Treat the heat loss to the surroundings by the two volumes and the rod as negligible. steam & water aluminum rod water & ice (a) Find the rate (in watts) at which heat is being transferred through the rod. (b) Find the rate (in grams per second) at which the steam is condensing.
Question 4If a copper kettle has a base of thickness 2 mm and area 3 x 10^-2 m², estimate the steady difference in temperature between inner and outer surfaces of the base which must be maintained to enable enough heat to pass through so that the temperature of 1 kg of water rises at the rate of 0.25 K s^-1. Assume that there are no heat losses, the thermal conductivity of copper = 380 Wm^-1K^-1. and the specific heat capacity of water is 4200 Jkg^-1 K^-1.
QUESTION 9 During the video on heat conduction, H through a single pane window was calculated. Now, consider a window that has wo panes with a 6 mm air gap between them. Each pane has an area of 1.9 m. The window separates the inside of a house at 22 °C from the outside at 0°C. Let Kair = 0.03 W/(m-K). Hint: This problem can be simplified by noting that the thermal conductivity of glass is much greater than air, so the effect of the glass on the total conductivity can be ignored. Therefore, the purpose of the two glass panes is to support the layer of air between them. Calculate the heat current H through the double glass pane window in watts. Do not include units in your answer and state your numerical answer in normal form.

1 Thermal Expansion A steel rod is 3.000 cm in diameter at 25 °C. A brass ring has an inner diameter of 2.992 cm at 25 °C. At what common temperature – i.e., the same temperature for the rod and ring – will the ring just fit onto the rod? The coefficient of linear expansion of steel is 11 x 10-6/°C. The coefficient of linear expansion of brass is 19 x 10-6/°C.
