The density of a uniform rod with cross-section A is d, its specific heat capacity is c and the coefficient of its linear expansion is . Calculate the amount of heat that should be added in order to increase the length of the rod by .
Options:
Answer:
A
Solution:
Required temperature rise is ΔT=l/(αL).
Rod mass is dAL, so Q=dALcΔT=dAcl/α.
