In the model bridge in the previous video, say the model is made out of copper and it is 1 meter long at room temperature, 25 Celsius. The model is heated to a temperature of 50 Celsius, and the expansion measured on the dial indicator is 0.4125 mm (this is 412.5*10^-6 meters or 412.5 μm). Using that information, calculate an experimental value of the thermal expansion coefficient in copper. Please use the formula from the video: AL = L.a.AT (the video explains each term) The expansion is so small that it is traditionally measured in parts per million. The answer for a can then be reported as x 10^-6 per degree Celsius. Report your answer as the number of millionths (that is, if you were to fill in the blank.) Your answer should be between 0 and 100.

Most automobiles have a coolant reservoir to catch radiator fluid than may overflow when 1he engine is hot. A radiator is made of copper and is filled to its 16.0L capacity when at 10.0C. What volume of radiator fluid will overflow when the radiator and fluid reach their 95.0C operating temperature, given that the fluid’s volume coefficient of expansion is =400106/C ? Note that this coefficient is approximate, because most car radiators have operating temperatures of greater than 95.0C.

ANSWER THE FF and SHOW COMPLETE SOLN: a.) An aluminum sheet of thickness 8.3 cm and area 13 m^2 is welded on top of a brass sheet of the same thickness and area. The thermal conductivities of aluminum and brass are 205 W/m·K and 109 W/m·K, respectively. The aluminum end is kept at 20 °C while the brass end is kept at 30 °C.

Suppose you want to raise the temperature of a mass m of ice from T0 < 0 °C to T > 100 °C. In this problem, represent the heat of fusion as Lf, the heat of vaporization as Lv, and the temperatures at which the phase changes occur as Tf and Tv. How much heat must be transferred for this to happen, including the energy needed for phase changes? Your answer should be in terms of the variables in the introduction and the specific heats of ice (ci), water (cw), and steam (cs). The talent heats are Lf= 334kJ/kg and Lv=2256kJ/kg?
