- A copper rod and an aluminum rod of equal diameter are joined end to end in good thermal contact. The temperature of the free end of the copper rod is held constant at 100°C, and that of the far end of the aluminum rod is held at 0°C. If the copper rod is 0.32 m long, what must be the length of the aluminum rod so that the temperature at the junction is 50°C? mYou drop an ice cube into an insulated flask full of water and wait for the ice cube to completely melt. The ice cube initially has a mass of 90.0 g and a temperature of 0°C. The water (before the ice cube is added) has a mass of 850 g and an initial temperature of 22.0°C. What is the final temperature (in °C) of the mixture? (Assume no energy is lost to the walls of the flask, or to the environment.) °CA copper rod and an aluminum rod of equal diameter are joined end to end in good thermal contact. The temperature of the free end of the copper rod is held constant at 100°C, and that of the far end of the aluminum rod is held at 0°C. If the copper rod is 0.50 m long, what must be the length of the aluminum rod so that the temperature at the junction is 50°C?

What is the final temperature in degrees Celsius?A copper rod and an aluminum rod of equal diameter are joined end to end in good thermal contact. The temperature of the free end of the copper rod is held constant at 100°C, and that of the far end of the aluminum rod is held at 0°C. If the copper rod is 0.42 m long, what must be the length of the aluminum rod so that the temperature at the junction is 50°C?Older railroad tracks in the U.S. are made of Part A 12-m-long pieces of steel. When the tracks are laid, gaps are left between the sections to prevent buckling when the steel thermally expands. If a track is laid at 16° C, how large should the gaps be if the track is not to buckle when the temperature is as high as 50° C? The coefficient of linear expansion of soft steel is 1.1 × 10-5 °C-1.
