The tallest buildng in tho world according to some architectural standards is the Taiper 101 in Tarean at a height of 1671 feet Assume that this height was measured on a cool spring day when the wmperature was 130 C. You could use the builáing as a sot of giant thermometer on a hot summer day by carefully measuring its height Suppose you do this and discover that the Tipe 101 is 0 473 foot taller than its official height My Answers Ghee U

Explanation / Answer

for steel, alpha = 13 x 10^-6 deg C  

deltaL = 0.473 ft

L0 = 1671 ft

delta(L) = L0 alpha deltaT  

0.473 = 1671 x 13 x 10^-6 (T - 13)

T = 34.8 deg C
