Write your solution on clean bond paper. Solutions must be in order. Show derivation of formulas and cancellation of units. Box the final answers. Late submission will not be accepted THERMAL EXPANSION 1. A wire that is 6.0 m long at 30 C is found to increase in length by 2.25 cm when heated to 700 C. Compute the coefficient of linear expansion. B) Find the stress in the wire if it is stretched taut at 700 C and cooled to 30 C without being allowed to contract. Y = 2.0 x 10 Pa. 2. A glass flask has a volume of 1000.00 ml at OC and is completely filled with Hg at this temperature. When flask and mercury were warmed to 50 C, 7.93 cm' of Hg overflow. If B. = 18 x 10s/ K, compute the coefficient of linear expansion for glass. 3. Suppose that liquid mercury and glass both had the same coefficient of volume expansion. Would a mercury-in-glass thermometer still work
