Steel aircraft carrier is 367 m long when moving through the icy North Atlantic at a temperature of 1.9°C?

Question

By how much does the carrier lengthen when it is traveling in the warm Mediterranean Sea at a temperature of 21°C?

Answer 1

Using the same coefficient of expansion n as answer 1, I get
dL = n*dT*L = 12E-6*19.2*367 = 0.08456 m, about a factor of 10 less. Note 12E-6 not 12E-6% is the correct coefficient.

Answer 2

It will expand 90.9924 centimeters after traveling south to the Mediterranean Sea. The Coefficient of expansion os steel is 12 x 10^ -6 % of the total length of the vessle.
Good luck.
