 At 21°C, a rod is exactly 22.82 cm long on a steel ruler. Both the rod and the ruler are placed in an oven at 240°C, where the rod now measures 23.03 cm on the same ruler. What is the coefficient of thermal expansion for the material of which the rod is made? The linear expansion coefficient of steel is

(a) an aluminum measuring rod, which is correct at 5.0 C measuresacertain distance as 88.42 cm at 35.0 C. Determine the errorinmeasuring the distance due to the expansion of the rod.
(b) if this aluminum rod measures a length of steel as 88.42cm at35.0 C, what is the correct length of the steel at 35degreesC. Thecoefficient of linear expansion of aluminum is 22 x10^-6C^-1.

answer to (a) .058cm
answer to (b) 88cm

can you help me to figure out how they got to these answers


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.
