/ 60 Physics 30 - Lesson 40H Thermodynamics Pg 205 1, 3-8 1) 1) expansion / contraction electrical conductivity / resistance color changes with temperature 3) The ring diameter will become larger since the linear expansion is greater than the volume expansion of the ring 4) The should be the original length. The change in length is proportional to the starting length. The final length should change as a result of temperature and coefficient of linear expansion. 5) Te hot ring lid is larger than the cool one and s therefore easier to remove (loosen) 6) Expansion and contraction of the long pipe on either end of the is compensated for by the “U” flexibility of the shape “U” 7) The value of 3.4ml /L /*C is true only for temperatures around 20*C. At different temperatures this value changes 8) Since the chimney expands and contracts with changes in temperature, any structure attached to it would move with the chimney. This would lead to structural damage of the house. 2) a) b) /4 3) a) b) /4
