A student measures the length of a brass rod with a steel tape at 293 K to be95.00 cm. What will the tape indicate for the length of the rod when both are at

(a) 258 K and

(b) 343 K?

Note that the steel tape and the rod will both be at the temperatures indicated for parts (a) and (b). The coefficients of thermal expansion are19*10-6K-1for brass and 11*10-6K-1for steel.
