Question

In the practice of linear expansion metal rod initially had a length of 600mm at a temperature of 21 ° C. was heated to 100 ° C and a length of 0610 mm therefore dilated, its coefficient of thermal linear expansion is:

12.8 X 10.6 mm / mm oC

10.8 X 10.6 mm / mm ° C-1

14.8 X 10.6 mm / mm ° C-1
