PHYS 2101 Lecture : Lecture 34
Document Summary
Solutions to test #4 will be posted very soon I"ll send out an email if so and over what 273. 15 (1 k = 1 c) 2) thermal contraction/expansion : linear with change in temperature. The change in length, l ( = l - l0 ), of almost all solids is ~ directly proportional to the change in temperature, t ( = t - t0 ) Rest of week: heat and temperature chapt. This is the last topic of the semester (chapt. The coefficient of thermal expansion of nickel/iron alloys is plotted here against the nickel percentage in the alloy. If two systems are in thermal equilibrium with a third, then they are in thermal equilibrium with each other. In this case: a) a is in thermal equilibrium with t b) b is in thermal equilibrium with t: a & b are in thermal equilibrium. If two objects are not in thermal equilibrium, their temperatures must be different.
