An aluminum rod is 23.5 cm long at 20°C and has a mass of 350 g. If 12000 J of energy is added to the rod by heat, what is the change in length of the rod?

An aluminum rod is 40.0 cm long and a steel rod is 30.0 cm longwhen both rods are at a temperature of 15. Both rods have the samediameter. The rods are joined end-to-end to form a rod 60.0 cmlong. The coefficients of linear expansion of aluminum and steelare 2.4 x 10-5 K-1 and 1.2 x 10-5 K-1, respectively. Thetemperature is raised to 110. The increase in the length of thejoined rod, in mm, is closest to:

a)1.1
b).88
c)1.4
d)1.0
e)1.3
