Figure 14.1a -120.0 cm- 33.4 cm 85.6 cm brass aluminum A brass rod is 33.4 cm long and an aluminum rod is 85.6 cm long when both rods are at an initial temperature of 0° C. The rods are placed in line with a gap of 1.0 cm between them. The distance between the far ends of the rods is maintained at 120.0 cm throughout. The temperature is raised until the two rods are barely in contact. The coefficients of linear expansion of brass and aluminum are 2.0 x 10-5 K and 2.4 x 10- K-, respectively. In Figure 14.1a, the temperature at which contact of the rods barely occurs, in °C, is closest to: A) 331 B) 349 C) 386 D) 404 E) 367
