A piece of copper tubing used in plumbing has a length of 60.0 cm at 20°C. When hot water at flows, the piece of copper’s temperature reaches to 85°C. What is the tube’s new length? The coefficient of linear thermal expansion of copper is 1.7 x 10-5 α(C°)-1

A metal rod has a starting length of 240 cm. When the temperature changes from 25 °C to 110 °C, the length of the rod changes 0.115 cm. What is the linear expansion coefficient of the rod?

Between 1793 and 1837, the U.S. penny was made entirely of copper and had a mass of 3.20 g. A coin collector accidentally drops one such penny from the balcony of his high-rise apartment, 36.0 m above the street. If 42.0% of the change in gravitational energy of the penny–Earth system is converted into internal energy of the penny, what is the increase in the temperature of the coin just before it impacts with the sidewalk? °C

A 1.50-kg iron horseshoe initially at 650°C is dropped into a bucket containing 13.0 kg of water at 22.0°C. What is the final temperature of the water-horseshoe system? Ignore the heat capacity of the container and assume a negligible amount of water boils away. °C

A steel beam 12 m sits next to a concrete wall when the temp is 20 degree A gap must be left between the beam and the concrete wall for expansion purposes. If the temp rises to 45 degrees C how large must the gap be if the steel beam just touches the concrete wall? Coefficient of linear expansion of steel 12X10-6 C-1.    I thought it was 1.20X10-3 but I was wronge  a. 3.60X10-3 b. 1.20X10-3 c. 2.40X10-3 d. 5.10X10-3

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.
