An aluminum bar 29 cm long and 6 cm by 7 cm on its sides is connected between two large metal blocks at temperatures of 138 °C and 19 °C, and energy is transferred from the hotter block to the cooler block at a rate Q₁. If instead the two blocks were connected by an aluminum bar that is 20 cm long and 3 cm by 3 cm on its sides, what would be the energy transfer rate? (Assume that the two large metal blocks are in contact with the sides of the aluminum bar so that energy is transferred along its length.) i Q₁

In a certain nanoparticle that behaves like the Einstein model, one quantum of energy equals 1.7 x 10-23 J, which is the smallest amount of energy that can be added to the nanoparticle. When the internal energy of the nanoparticle is equal to 1500 quanta, there are 1.929 x 1061 ways to arrange these 1500 quanta of energy in the nanoparticle. If one more quantum of energy is added to the nanoparticle, the number of ways to arrange the 1501 quanta of energy increases to 1.966 x 1061. What is the absolute temperature of this nanoparticle? Recall that kB = 1.38 x 10-23 J/K. T = Mi K

A (nearly) reversible engine is used to melt ice as well as do some useful work. If the engine does 1072 J of work and dumps 384 J into the ice, what is the temperature of the high-temperature source? i !K
