Q 1. A brass rod and a lead rod each 80 cm long at 0 degree celsius are clamped together at one end with their free end coinciding. The seperation of the free ends of the rod if the system is placed in a steam bath at 100 degree celsius is ( coefficient of linear expansion of lead = 28*10^-6/degree celsius, coefficent of linear expansion of brass
= 18 * 10^-6/degree celsius) :
a. 0.2 mm
b. 0.8 mm
c. 1.4 mm
d 1.6 mm

Kindly Answer the above with the explanation

Show us your work and where you got stuck. What's the basic equation describing thermal expansion?

is this the answer???

:smile:
0.8 because the formula is delta L=(alpha) (L initial)(delta Temp.)
